| jQuery and Microsoft ... jQuery is a lightweight open source JavaScript library (only 15kb in size) that in a relatively short span of time has become one of the most popular libraries on the web. A big part of the appeal of jQuery is that it allows you to elegantly (and efficiently) find and manipulate HTML elements with minimum lines of code. jQuery supports this via a nice "selector" API that allows developers to query for HTML elements, and then apply "commands" to them. One of the characteristics of jQuery commands is that they can be "chained" together - so that the result of one command can feed into another. jQuery also includes a built-in set of animation APIs that can be used as commands. The combination allows you to do some really cool things with only a few keystrokes. For example, the below JavaScript uses jQuery to find all <div> elements within a page that have a CSS class of "product", and then animate them to slowly disappear: As another example, the JavaScript below uses jQuery to find a specific <table> on the page with an id of "datagrid1", then retrieves every other <tr> row within the datagrid, and sets those <tr> elements to have a CSS class of "even" - which could be used to alternate the background color of each row: [Note: both of these samples were adapted from code snippets in the excellent jQuery in Action book] Providing the ability to perform selection and animation operations like above is something that a lot of developers have asked us to add to ASP.NET AJAX, and this support was something we listed as a proposed feature in the ASP.NET AJAX Roadmap we published a few months ago. As the team started to investigate building it, though, they quickly realized that the jQuery support for these scenarios is already excellent, and that there is a huge ecosystem and community built up around it already. The jQuery library also works well on the same page with ASP.NET AJAX and the ASP.NET AJAX Control Toolkit. Rather than duplicate functionality, we thought, wouldn't it be great to just use jQuery as-is, and add it as a standard, supported, library in VS/ASP.NET, and then focus our energy building new features that took advantage of it? We sent mail the jQuery team to gauge their interest in this, and quickly heard back that they thought that it sounded like an interesting idea too. Supporting jQuery I'm excited today to announce that Microsoft will be shipping jQuery with Visual Studio going forward. We will distribute the jQuery JavaScript library as-is, and will not be forking or changing the source from the main jQuery branch. The files will continue to use and ship under the existing jQuery MIT license. We will also distribute intellisense-annotated versions that provide great Visual Studio intellisense and help-integration at design-time. For example: and with a chained command: The jQuery intellisense annotation support will be available as a free web-download in a few weeks (and will work great with VS 2008 SP1 and the free Visual Web Developer 2008 Express SP1). The new ASP.NET MVC download will also distribute it, and add the jQuery library by default to all new projects. We will also extend Microsoft product support to jQuery beginning later this year, which will enable developers and enterprises to call and open jQuery support cases 24x7 with Microsoft PSS. Going forward we'll use jQuery as one of the libraries used to implement higher-level controls in the ASP.NET AJAX Control Toolkit, as well as to implement new Ajax server-side helper methods for ASP.NET MVC. New features we add to ASP.NET AJAX (like the new client template support ) will be designed to integrate nicely with jQuery as well. We also plan to contribute tests, bug fixes, and patches back to the jQuery open source project. These will all go through the standard jQuery patch review process. Summary We are really excited to be able to partner w | Go |
| Silverlight 2 Release Candidate Now Available ... This evening we published the first public release candidate of Silverlight 2. There are still a small handful of bugs fixes that we plan to make before we finally ship. We are releasing today's build, though, so that developers can start to update their existing Silverlight Beta2 applications so that they'll work the day the final release ships, as well as to enable developers to report any last minute showstopper issues that we haven't found internally (please report any of these on the www.silverlight.net forums). Important: We are releasing only the Silverlight Developer Runtime edition (as well as the VS and Blend tools to support it) today, and are not releasing the regular end-user edition of Silverlight. This is because we want to give existing developers a short amount of time to update their applications to work with the final Silverlight 2 APIs before sites are allowed to go live with it. There are some breaking changes between Beta2 and this RC, and we want to make sure that existing sites can update to the final release quickly once the final release is out. As such, you can only use the RC for development right now - you can't go live with the new APIs until the final release is shipped (which will be soon though). You can download today's Silverlight Release Candidate and accompanying VS and Blend support for it here . Note that Expression Blend support for Silverlight 2 is now provided using Blend 2.0 SP1. You will need to install Blend 2.0 before applying the SP1 service pack that adds Silverlight 2 support. If you don't already have Blend 2.0 installed you can download a free trial of it here . Beta2->RC API Updates Today's release candidate includes a ton of bug fix and some significant performance optimization work. Today's release candidate also includes a number of final API tweaks designed to fix differences between Silverlight and the full .NET Framework. Most of these changes are relatively small (order of parameters, renames of methods/properties, movement of types across namespaces, etc) although there are a number of them. You can read this blog post and download this document to get a listing of the known API breaking changes made from the Beta2 release. We have updated the styles of the controls shipped with Silverlight, and have also modified some of the state groups and control template names they use. When upgrading from Beta2 you might find it useful to temporarily remove any custom style templates you've defined, and get your application functionality working using the RC first - and then after that works add back in the styles one style definition at a time to catch any rename/behavior change issues with them. If you find yourself stuck with an question/issue moving from Beta2 to the RC, please report it on the www.silverlight.net forums (Silverlight team members will be on there helping folks). If after a day or two you aren't getting an answer please send me email (scottgu@microsoft.com ) and I can help or connect you with someone who knows the answer. New Controls Today's release candidate includes a bunch of feature additions and tweaks across Silverlight 2, as well as in the VS and Blend tools targeting it. In general you'll find a number of nice improvements across the controls, networking, data caching, layout, rendering, media stack, and other components and sub-systems. Over the next few months we will be releasing a lot of new Silverlight 2 controls (more details on these soon). Today's release candidate includes three new core controls - ComboBox, ProgressBar, and PasswordBox - that we are adding directly to the core Silverlight runtime download (which is still only 4.6MB in size, and only takes a few seconds to install): At runtime these controls by default look like: The ComboBox in Silverlight 2 supports standard DropDownList semantics. In addition to statically defining items like above, you | Go |
| ASP.NET MVC Preview 5 and Form Posting Scenarios ... This past Thursday the ASP.NET MVC feature team published a new "Preview 5" release of the ASP.NET MVC framework. You can download the new release here . This "Preview 5" release works with both .NET 3.5 and the recently released .NET 3.5 SP1. It can also now be used with both Visual Studio 2008 as well as (the free) Visual Web Developer 2008 Express SP1 edition (which now supports both class library and web application projects). Preview 5 includes a bunch of new features and refinements (these build on the additions in "Preview 4" ). You can read detailed "Preview 5" release notes that cover changes/additions here . In this blog post I'm going to cover one of the biggest areas of focus with this release: form posting scenarios. You can download a completed version of the application I'll build below here . Basic Form Post with a Web MVC Pattern Let's look at a simple form post scenario - adding a new product to a products database: The page above is returned when a user navigates to the "/Products/Create" URL in our application. The HTML form markup for this page looks like below: The markup above is standard HTML. We have two <input type="text"/> textboxes within a <form> element. We then have an HTML submit button at the bottom of the form. When pressed it will cause the form it is nested within to post the form inputs to the server. The form will post the contents to the URL indicated by its "action" attribute - in this case "/Products/Save". Using the previous "Preview 4" release of ASP.NET we might have implemented the above scenario using a ProductsController class like below that implements two action methods - "Create" and "Save": The "Create" action method above is responsible for returning an html view that displays our initial empty form. The "Save" action method then handles the scenario when the form is posted back to the server. The ASP.NET MVC framework automatically maps the "ProductName" and "UnitPrice" form post values to the method parameters on the Save method with the same names. The Save action then uses LINQ to SQL to create a new Product object, assigns its ProductName and UnitPrice values with the values posted by the end-user, and then attempts to save the new product in the database. If the product is successfully saved, the user is redirected to a "/ProductsAdded" URL that will display a success message. If there is an error we redisplay our "Create" html view again so that the user can fix the issue and retry. We could then implement a "Create" HTML view template like below that would work with the above ProductsController to generate the appropriate HTML. Note below that we are using the Html.TextBox helper methods to generate the <input type="text"/> elements for us (and automatically populate their value from the appropriate property in our Product model object that we passed to the view): Form Post Improvements with Preview 5 The above code works with the previous "Preview 4" release, and continues to work fine with "Preview 5". The "Preview 5" release, though, adds several additional features that will allow us to make this scenario even better. These new features include: The ability to publish a single action URL and dispatch it differently depending on the HTTP Verb Model Binders that allow rich parameter objects to be constructed from form input values and passed to action methods Helper methods that enable incoming form input values to be mapped to existing model object instances within action methods Improved support for handling input and validation errors (for example: automatically highlighting bad fields and preserving end-user entered form values when the form is redisplayed to the user) I'll use the remainder of this blog post to drill into each of these scenarios. [AcceptVerbs] and [ActionName] attributes In our sample above we implemented ou | Go |
| Quick Update ... I've received a number of (very nice) emails recently asking if I was ok - since my blog has been silent the last few weeks (and much of the summer). Just to address people's concerns - I'm alive and well. :-) I've just been on vacation the last 6 weeks, and have unfortunately not had free time to post (I've been changing a lot of diapers). I am still on vacation another week before I officially return to work. I did get a chance to write up a quick post this weekend that covers some of the new ASP.NET MVC Preview 5 features, though, that will hopefully provide some interim reading until I can resume a more regular posting schedule over the next month when I get back into the office. Thanks, Scott P.S. Somewhat to my embarrassment I started a Part1/Part2 post on "Preview 4" right before I left for vacation, and didn't have time to finish part 2 before "Preview 5" came out. I am going to post this lost segment (which covered AJAX) later this month and write it against the latest preview build. P.P.S. People often ask me whether I write my own blog. Yep - I actually really do write every single post. Hopefully my absence the last 6 weeks provides some evidence to support this. :-) | Go |
| ASP.NET MVC Preview 4 Release (Part 1) ... The ASP.NET MVC team is in the final stages of finishing up a new "Preview 4" release that they hope to ship later this week. The Preview 3 release focused on finishing up a lot of the underlying core APIs and extensibility points in ASP.NET MVC. Starting with Preview 4 this week you'll start to see more and more higher level features begin to appear that build on top of the core foundation and add nice productivity. There are a bunch of new features and capabilities in this new build - so much in fact that I decided I needed two posts to cover them all. This first post will cover the new Caching, Error Handling and Security features in Preview 4, as well as some testing improvements it brings. My next post will cover the new AJAX features being added with this release as well. Understanding Filter Interceptors Action Filter Attributes are a useful extensibility capability in ASP.NET MVC that was first added with the "Preview 2" release. These enable you to inject code interceptors into the request of a MVC controller that can execute before and after a Controller or its Action methods execute. This enables some nice encapsulation scenarios where you can easily package-up and re-use functionality in a clean declarative way. Below is an example of a super simple "ScottGuLog" filter that I could use to log details about exceptions raised during the execution of a request. Implementing a custom filter class is easy - just subclass the "ActionFilterAttribute" type and override the appropriate methods to run code before or after an Action method on the Controller is invoked, and/or before or after an ActionResult is processed into a response. Using a filter within a ASP.NET MVC Controller is easy - just declare it as an attribute on an Action method, or alternatively on the Controller class itself (in which case it will apply to all Action methods within the Controller): Above you can see an example of two filters being applied. I've indicated that I want my "ScottGuLog" to be applied to the "About" action method, and that I want the "HandleError" filter to be applied to all Action methods on the HomeController. Previous preview releases of ASP.NET MVC enabled this filter extensibility, but didn't ship with pre-built filters. ASP.NET Preview 4 now includes several useful filters for handling output caching, error handling and security scenarios. OutputCache Filter The [OutputCache] filter provides an easy way to integrate ASP.NET MVC with the output caching features of ASP.NET (with ASP.NET MVC Preview 3 you had to write code to achieve this). To try this out, modify the "Message" value set within the "Index" action method of the HomeController (created by the VS ASP.NET MVC project template) to display the current time: When you run your application you'll see that a timestamp updates each time you refresh the page: We can enable output caching for this URL by adding the [OutputCache] attribute to the our Action method. We'll configure it to cache the response for a 10 second duration using the declaration below: Now when you hit refresh on the page you'll see that the timestamp only updates every 10 seconds. This is because the action method is only being called once every 10 seconds - all requests between those time intervals are served out of the ASP.NET output cache (meaning no code needs to run - which makes it super fast). In addition to supporting time duration, the OutputCache attribute also supports the standard ASP.NET output cache vary options (vary by params, headers, content encoding, and custom logic). For example, the sample below would save different cached versions of the page depending on the value of an optional "PageIndex" QueryString parameter, and automatically render the correct version depending on the incoming URL's querystring value: You can also integrate with the ASP.NET Database Cache Invalidation feature - which allows you t | Go |
| Silverlight 2 Beta2 Released ... Silverlight 2 Beta2 was released today. You can download both Silverlight 2 Beta2 and the Visual Studio and Expression Blend tools support to target it here . Beta2 adds a lot of new features (more details below), but is still a 4.6 MB download that takes less than 10 seconds to install on a machine. It does not require the .NET Framework or any other software to be installed for it to work, and all features work cross-browser on both Mac and Windows machines. These features will also be supported on Linux via the Moonlight 2 release. Silverlight 2 Beta2 supports a go-live license that allows you to start using and deploying Silverlight 2 for commercial applications. There will be some API changes between Beta2 and the final release, so you should expect that applications you write with Beta2 will need to make some updates when the final release comes out. But we think that these changes will be straight-forward and relatively easy, and that you can begin planning and starting commercial projects now. You can build Silverlight Beta2 applications using the VS 2008 Tools for Silverlight and Expression Blend 2.5 June Preview downloads. You can download both of them here . The VS 2008 Tools for Silverlight download works with both VS 2008 and the recent VS 2008 SP1 beta release. UI and Control Improvements Silverlight 2 Beta2 includes a bunch of work in the UI and Control space: More Built-in Controls In Beta 1 only a few controls were included with the core Silverlight setup. Most common controls (including Button, ListBox, Slider, etc) were shipped within separate assemblies that you had to bundle with your applications (which increased the app download size). Beta 2 now installs 30+ of the most common controls as part of the core Silverlight 2 download. This means that you can now build Silverlight 2 applications that use core controls that are as small as 3kb in size - making Silverlight application downloads small and startup time fast. In addition to the core controls included with the base Silverlight 2 setup, we are also this week shipping additional higher-level controls that are implemented in separate assemblies that you can then reference and include with your applications. This includes controls like DataGrid (more details on its new Beta2 features below), Calendar (now with multi-day selection and blackout date support in Beta2), and a TabPanel control (new in Beta2). We ultimately expect to ship over a 100 controls for Silverlight. Control Template Editing Support One of the most powerful features of the WPF and Silverlight programming model is the ability to completely customize the look and feel of controls. This allows developers and designers to sculpt the UI of controls in both subtle and dramatic ways, and enables a tremendous amount of flexibility. I covered these concepts a little in my previous Silverlight Control Templating blog post here . This week's Expression Blend 2.5 June Preview now adds designer support for editing control templates - which makes it easy for you to quickly change the look of any control without having to drop-down to XAML source to-do it. To see control template editing in action, just drag/drop two Slider controls onto the Expression Blend design surface: We might decide that the slider head in the default Slider control template is too large and wide for our application. To use control template editing to change it, we can right-click on one of the sliders in the designer and select the "Edit Control Parts" context menu item. We can choose to create a new empty control template for our slider (and start from scratch), or alternatively edit a copy of the built-in control template (and start from that and tweak it): After we choose to edit a copy of the existing control template, Blend will prompt us to create and name a re-usable style resource that we'll define our control template wit | Go |
| ASP.NET MVC Support with Visual Web Developer 2008 Express ... Last week I blogged about the ASP.NET MVC Preview 3 release . One important thing I forgot to mention about this release is that you can now use it with both Visual Studio 2008 as well as the free Visual Web Developer 2008 Express edition. The SP1 release of Visual Web Developer 2008 Express adds support for both class library projects as well as web application projects (previously only web site projects could be used with it). This new support is useful in itself, as well as in enabling both ASP.NET MVC and Silverlight project support with VWD Express. If you install the Visual Web Developer Express SP1 Beta you can start using ASP.NET MVC Preview 3 with it immediately. Important: ASP.NET MVC Preview 3 does not require SP1 to be installed if you are using Visual Studio 2008. ASP.NET MVC Preview 3 will work with both VS 2008 and VS 2008 SP1 just fine. You can learn more about the new VWD Express support for ASP.NET MVC from the VS Web Tools team blog here . This post also includes a free web download that provides ASP.NET MVC Test project support for NUnit-based unit tests. You can use these NUnit project templates with both Visual Studio 2008 as well as with Visual Web Developer Express 2008. Hope this helps, Scott | Go |
| ASP.NET MVC Preview 3 Release ... This morning we released the Preview 3 build of the ASP.NET MVC framework. I blogged details last month about an interim source release we did that included many of the changes with this Preview 3 release. Today's build includes some additional features not in last month's drop, some nice enhancements/refinements, as well as Visual Studio tool integration and documentation. You can download an integrated ASP.NET MVC Preview 3 setup package here . You can also optionally download the ASP.NET MVC Preview 3 framework source code and framework unit tests here . Controller Action Method Changes ASP.NET MVC Preview 3 includes the MVC Controller changes we first discussed and previewed with the April MVC source release , along with some additional tweaks and adjustments. You can continue to write controller action methods that return void and encapsulate all of their logic within the action method. For example: which would render the below HTML when run: Preview 3 also now supports using an approach where you return an "ActionResult" object that indicates the result of the action method, and enables deferred execution of it. This allows much easier unit testing of actions (without requiring the need to mock anything). It also enables much cleaner composition and overall execution control flow. For example, we could use LINQ to SQL within our Browse action method to retrieve a sequence of Product objects from our database and indicate that we want to render a View of them. The code below will cause three pieces of "ViewData" to be passed to the view - "Title" and "CategoryName" string values, and a strongly typed sequence of products (passed as the ViewData.Model object): One advantage of using the above ActionResult approach is that it makes unit testing Controller actions really easy (no mocking required). Below is a unit test that verifies the behavior of our Browse action method above: We can then author a "Browse" ViewPage within the \Views\Products sub-directory to render a response using the ViewData populated by our Browse action: When we hit the /Products/Browse/Beverages URL we'll then get an HTML response like below (with the three usages of ViewData circled in red): Note that in addition to support a "ViewResult" response (for indicating that a View should be rendered), ASP.NET MVC Preview 3 also adds support for returning "JsonResult" (for AJAX JSON serialization scenarios), "ContentResult" (for streaming content without a View), as well as HttpRedirect and RedirectToAction/Route results. The overall ActionResult approach is extensible (allowing you to create your own result types), and overtime you'll see us add several more built-in result types. Improved HTML Helper Methods The HTML helper methods have been updated with ASP.NET MVC Preview 3. In addition to a bunch of bug fixes, they also include a number of nice usability improvements. Automatic Value Lookup With previous preview releases you needed to always explicitly pass in the value to render when calling the Html helpers. For example: to include a value within a <input type="text" value="some value"/> element you would write: The above code continues to work - although now you can also just write: The HTML helpers will now by default check both the ViewData dictionary and any Model object passed to the view for a ProductName key or property value to use. SelectList and MultiSelectList ViewModels New SelectList and MultiSelectList View-Model classes are now included that provide a cleaner way to populate HTML dropdowns and multi-select listboxes (and manage things like current selection, etc). One approach that can make form scenarios cleaner is to instantiate and setup these View-Model objects in a controller action, and then pass them in the ViewData dictionary to the View to format/render. For example, below I'm creating a SelectList view-model class over the | Go |
| May 20th Links: ASP.NET, ASP.NET AJAX, .NET, Visual Studio, Silverlight, WPF ... Apologies for the sparseness of my posting the last few weeks - work and life have been busy here lately. Below is a new post in my link-listing series to help kick things up a little. Also check out my ASP.NET Tips, Tricks and Tutorials page and Silverlight Tutorials page for links to popular articles I've done myself in the past. ASP.NET Bulk Inserting Data with the ListView Control : Matt Berseth continues his awesome posts with one that shows how to handle bulk-editing of data using the ASP.NET ListView control in .NET 3.5. Master-Detail with the GridView, DetailsView, and ModalPopup Controls : Another great post from Matt that describes how to cleanly handle a common data entry scenario.

| Visual Studio 2008 and .NET Framework 3.5 Service Pack 1 Beta ... Earlier today we shipped a public beta of our upcoming .NET 3.5 SP1 and VS 2008 SP1 releases. These servicing updates provide a roll-up of bug fixes and performance improvements for issues reported since we released the products last November. They also contain a number of feature additions and enhancements that make building .NET applications better (see below for details on some of them).
We plan to ship the final release of both .NET 3.5 SP1 and VS 2008 SP1 this summer as free updates. You can download and install the beta here .
Important: SP1 Beta Installation Notes
The SP1 beta released today is still in beta form - so you should be careful about installing it on critical machines. There are a few important SP1 Beta installation notes to be aware of:
1) If you are running Windows Vista you should make sure you have Vista SP1 installed before trying to install .NET 3.5 SP1 Beta. There are some setup issues with .NET 3.5 SP1 when running on the Vista RTM release. These issues will be fixed for the final .NET 3.5 SP1 release - until then please make sure to have Vista SP1 installed before trying to install .NET 3.5 SP1 beta.
2) If you have installed the VS 2008 Tools for Silverlight 2 Beta1 package on your machine, you must uninstall it - as well as uninstall the KB949325 update for VS 2008 - before installing VS 2008 SP1 Beta (otherwise you will get a setup failure). You can find more details on the exact steps to follow here (note: you must uninstall two separate things). It is fine to have the Silverlight 2 runtime on your machine with .NET 3.5 SP1 - the component that needs to be uninstalled is the VS 2008 Tools for Silverlight 2 package. We will release an updated VS 2008 Tools for Silverlight package in a few weeks that works with the VS 2008 SP1 beta.
3) There is a change in behavior in the .NET 3.5 SP1 beta that causes a problem with the shipping versions of Expression Blend. This behavior change is being reverted for the final .NET 3.5 SP1 release, at which time all versions of Blend will have no problems running. Until then, you need to download this recently updated version of Blend 2.5 to work around this issue.
Important Update : If you previously installed a VS 2008 Hotfix, you must run the HotFix Cleanup Utility before installing the VS 2008 SP1 Beta. Click here to download and run this.
Improvements for Web Development
.NET 3.5 SP1 and VS 2008 SP1 contain a bunch of feature improvements targeted at web application development.
The VS Web Dev Tools team has more details (including specific bug fix details) on some of the VS specific work here . Below are more details on some of the work in the web-space:
ASP.NET Data Scaffolding Support (ASP.NET Dynamic Data)
.NET 3.5 SP1 adds support for a rich ASP.NET data "scaffolding" framework that enables you to quickly build functional data-driven web application. With the ASP.NET Dynamic Data feature you can automatically build web UI (with full CRUD - create, read, update, delete - support) against a variety of data object models (including LINQ to SQL, LINQ to Entities, REST Services, and any other ORM or object model with a dynamic data provider).
SP1 adds this new functionality to the existing GridView, ListView, DetailsView and FormView controls in ASP.NET, and enables smart validation and flexible data templating options. It also delivers new smart filtering server controls, as well as adds support for automatically traversing primary-key/foreign-key relationships and displaying friendly foreign key names - all of which saves you from having to write a ton of code.
You can learn more more about this feature from Scott Hanselman's videos and tutorials here .
ASP.NET Routing Engine (System.Web.Routing)
.NET 3.5 SP1 includes a flexible new URL routing engine that allows you to map incoming URLs to route handlers. It includes support for both parsing parameters from clean URLs (for example: /Products/Browse/Beverages), as well as supp | Go |
| Professional ASP.NET 3.5 Book (only $16 on Amazon for a short time) ... One of the things I like to track are book sales on Amazon.com, which provides a useful data point to monitor what developers are interested in on any given day. I use the www.TitleZ.com site (which is built using ASP.NET) to track specific titles I want to watch - it then generates a report showing real-time Amazon sales ranking data, as well as 7 day, 30 day and 90 day sales ranking averages. This morning I pulled up my report and saw the usual books near the top of my list, and was about to navigate away when I noticed the eye-popping amazon ranking of the top book -"Professional ASP.NET 3.5: In C# and VB " by Bill Evjen, Scott Hanselman and Devin Rader. Its Amazon sales rank was a stunning #95 (of all books on Amazon), which meant it was outselling even Harry Potter (which is pretty much unheard of for any technology book). It turns out that Amazon is holding a special price promotion for a short time on a few books - and this was one that was selected. Instead of the usual $54 price, you can buy it for a short time for a ridiculous $16.49. I'm not sure how long this promotion will last - but if you are looking for a great ASP.NET 3.5 book this might be something you might want to take advantage of: The book is a great ASP.NET 3.5 book and an excellent end to end resource. It has been on the best seller list for programming books since it came out in March (usually in the top 5 of all programming titles), and has received glowing reviews (I posted a review of it on Amazon a few weeks ago and gave it 5 stars). If you are in the market for a good ASP.NET book, you might want to consider taking Amazon up on this offer before it closes (and apologies in advance if the price changes before you read this). Hope this helps, Scott P.S. If you are looking for other good .NET 3.5 and VS 2008 books - I also recommend: C# 3.0 In a Nutshell , LINQ in Action , and Pro LINQ: Language Integrated Query in C# 2008 (all of which average a 5 star rating on Amazon). | Go |

| Search Trends October 2008 ... PDC is fast approaching and Cloud Computing is the theme - and all the rage for everyone else in the Industry media. Amazon recently announced they'll be extending their compute cloud to support Windows and real databases. Here's a look at some recent trends in the tech industry, using Google Trends . Daylight Savings Time The topic of DST is likely of at least marginal interest to most software developers, as working with DateTime constructs is a frequent requirement for us (and often a source of frustration). I wanted to confirm when it was this year and that led to the rest of these trend searches (I once missed a flight due to a change in the date of DST that my alarm clock's auto adjustment failed to pick up). FYI: Daylight Savings Time in 2008 will Fall Back the first Sunday in November. Interesting (and expected) that twice a year folks become interested in this topic. Note that the main regions who care are US, Canada, Australia, and the UK. Most of the world doesn't observe DST. And contrary to what I thought I knew, Ben Franklin didn't invent DST and it only started in the early 1900s (according to the Source Of All Knowledge: Wikipedia ). Cloud Computing If I were a betting man, I'd bet on cloud computing to be a big upcoming trend in the next several years. It first hit the search term scene a little over a year ago, and it's gone up rather drastically since then. I'd look for it to peak in November this year after PDC and then to plateau or rise gently after that. Amazon's S3 and EC2 services have been around for a while - let's see how Microsoft compares thus far. Amazon Cloud vs. Microsoft Cloud I'd say Microsoft is going to catch and surpass Amazon by PDC time. Looking at another Microsoft event and announcement, let's see how Silverlight is doing in terms of interest. Silverlight Silverlight is still going strong. I predict it will go up steadily once Silverlight 2 is released, slated for later this year and most likely at PDC, I would say. So what about hosting? Is anyone looking for cloud hosting solutions? Compared to what? Let's look at two comparably small sets of terms. Cloud vs. Ruby Hosting Cloud hosting didn't exist as a trend before 2008 Q3 and now it's nearly as popular a search term as ruby hosting. Clearly Ruby Hosting isn't all that popular, but just how does it compare to say ASP.NET and PHP? Ruby vs. ASP.NET vs. PHP Hosting Clearly the trends for all three of these are heading downward, as I think the hosting marketplace has largely shaken out and become somewhat commoditized. With sites like GoDaddy offering cheap hosting along with about a million easy to use web publishing and blogging platforms, the need for hosting is obviously in decline. So what else is new? What about ASP.NET? Remember when it was Atlas? And what about this new jQuery thing that's not really new but is now going to ship with Visual Studio? Atlas vs. ASP.NET AJAX ... and jQuery How about data access technologies? Would it surprise you to learn that NHibernate has been a search trend since late 2004, with greater popularity than either LINQ to SQL or Entity Framework's high water mark since 2006 (that is, NH's 2006 and later popularity exceeds the best the others have ever achieved). I doubt this reflects adoption, but it's interesting nonetheless. Perhaps it reflects people searching for documentation... NHibernate vs. LINQ to SQL vs. Entity Framework How is interest in ASP.NET MVC coming along, with its hopeful release some time in 2008 as well? ASP.NET MVC Lastly, in the self-fulfilling prophecy department, how many people have been looking for a recession, since about a year ago? It certainly appears the popularity of a recession has gone up dramatically in the last 12 months.

WebForms has the Control model where markup and logic live together and can be composed easily. With the MVC Framework CTP 5, a single...

| Being a software engineer in a bad economy ... Make friends and family are a little worried about “these bad economy”, many articles are coming out or even books about how to deal with a recession. One good book that just came out is; Bulletproof your job , the message is clear, be visible, easy and ready at your company. Make sure you work in projects that are visible to the big heads, make sure you do not complain or make things hard, and be ready for any extra work or travelling.
I also would thing that every company is different, at recession time, big companies are stronger than small companies with small amount of money in the bank. So even you following all the experts, you can find yourself without a job in a few months.
I have seen software developers trying to get visible in the .NET community right now, I believe this is because they want to use the networking in case they need to apply for a job. In my opinion, if you are not sure about your company , make sure to make the change now to a company that can go through any economy slow down without having to lay off people, what are those companies? Well for starters companies that are still recruiting is a good sign, many now have implemented a hiring freeze, some still need more programmers. Like Tellingent , a software company based in Dallas TX and creators of the Community Server .
Another way to find a software job is to look at the hidden networks for local jobs and find the companies they are still applying. I would personally stay away from big hiding websites. Hidden networks are companies that want a direct contact with the software developer.
Robert Scobler is blogging every day about the economy world instead of the tech world, as this is the main concern looks like. Still I believe that now more than ever. Famous bloggers with many followers are worrying the professional lately.
Please share with me the stories about being a software developer or IT professional in this worried times. What are your plans? How is the market where you are?
Cheers

| SharpMock 0.1 ? ... James, I would love to see you take the idea of “SharpMock” to the next level . If not anything else, it would be an interesting challenge to write about. James took PostSharp and started looking at the possibility of intercepting static method calls using it’s code weaving API. Nice idea! James, you are totally deserving a free Typemock Isolator Pro license for your efforts. Ping me at royo at Typemock.com and I’ll hook you up! | Go |
| Points of interest #11 - Silverlight, Open Source ... I've decided to restart my "Points of interest" posts. To get the ball rolling I'll start off small: Open Source Old news but Jitterbit 2.0 was released in August . http://www.jitterbit.com The Jitterbit Integration Solution combines intuitive integration
design with robust functionality and scalable performance. Jitterbit is
designed to handle the most complex integration challenges between
legacy, enterprise and On-Demand applications, including Business Process Fusion , ETL , SaaS , and SOA .
The Jitterbit Solution enables organizations to unite their independent
applications and data in record time and for the lowest total cost of
ownership in the industry. Not specific to .Net but may prove useful for those looking for a way of performing an integration between multiple systems without having to create something yourself or purchase a licence. In September Solr 1.3 was released . http://lucene.apache.org/solr/ Solr is an open source enterprise search server based on the
Lucene Java search library, with XML/HTTP and JSON APIs,
hit highlighting, faceted search, caching, replication, a web administration interface and many more features.
It runs in a Java servlet container such as Tomcat .
Again not specific to .Net but very useful. Was just thinking about the possibility of a database (whatever your preference), Jitterbit, Solr and a Silverlight front end.........talking about Silverlight............. Silverlight Big news coming this Monday about Silverlight !! Can't remember the source (sorry! please add it as a comment and I'll add your link) but someone mentioned that he monitors Microsoft's press pass releases and came across this: Microsoft Corp. will hold a teleconference with Scott Guthrie,
corporate vice president of the .NET Developer Division at Microsoft.
Guthrie will make a significant announcement related to Microsoft
Silverlight. Now this could be that Silverlight is released or a date is announced. I'm not 100% sure on it being a release announcement as it has only been a few weeks since RC1 came out and people are still busy updating their beta 2 projects. I hope if it is a date announcement it isn't something along the lines of December 08 (or Mix 09 :D). I assumed it would be released at the PDC but if they are running late then this would make a date announcement essential in order to manage expectations. Out of the two options I think I would prefer it to be an announcement that Silverlight is now live. The argument for that is that they want to make sure other PDC announcements do not get drowned out with news that Silverlight has been released. http://www.microsoft.com/presspass/press/2008/oct08/10-10GuthrieSilverlightMA.mspx That's all for now. | Go |

One of my work needs was to open OWA inside our web application to
make clients more related with the application and let them easy access their
emails while working. After some researches i found a simple way to do that, actually
it is not that much hard to find the code below, but you have to search well to
find it!. An here is the way that i have done that, we have a page with 2
iframes inside it. Upper frame holds the links banner and the bottom frame
which holds whatever is clicked from the links banner. The work is to open OWA
inside the bottom Banner. To open OWA you have to create a small JavaScript for
that which will send the user name and password to be authenticated in from
owaauth.dll and if everything goes fine you'll successed to open your email.
The code is as below;
public partial class OpenOwaPage : System.Web.UI.Page
{
private string userName;
private string passWord;
protected void Page_Load(object sender, EventArgs e)
{
passWord =
"password";
userName
="username";
Response.Write(CreateOWAFrom());
Response.Write(LoadOWAPostJS("logonForm"));
}
private string LoadOWAPostJS(string strFormId)
{
//Constructs the JS needed to post
the data to Realex and returns it
StringBuilder strScript = new
StringBuilder();
strScript.Append("<script
language='javascript'>");
strScript.Append("var ctlForm =
document.forms.namedItem('{0}');");
strScript.Append("ctlForm.username.value=\"" + userName +
"\";");
strScript.Append("ctlForm.password.value=\"" + passWord +
"\";");
strScript.Append("ctlForm.submit();");
strScript.Append("</script>");
return
String.Format(strScript.ToString(), strFormId);
}
private string CreateOWAFrom()
{
//Constructs the Realex HTML form
and returns it
StringBuilder strForm = new
StringBuilder();
strForm.AppendLine("<form
id=\"logonForm\" name=\"logonForm\"
target=\"_self\"

strForm.AppendLine("<input

| In Search For Agile Domain Driven Design … Hopefully Part 1 of N ... The Useless Introduction You Used To :)
This post has taken so long to be started in writing. I’ve been busy with many events in my life lately. Suffering from frequent limited internet access lately, and, all this moving between companies thing has been eating me. And yes, I admit, I' have been as tired and more honestly lazy as you expected me to be!
Hey, there’s a little warning. This post is not exactly for my usual audience. I’m sorry, but introducing Domain Driven Design is not one of the goals for this post. There’re many interesting resources and books (even FREE: InfoQ, Domain Driven Design Quickly ) on the topic. However, if you leave me a comment telling me to make a write-up on the topic, of course I will :) :).
One more thing. Another reason I’m working on this is that I’m preparing for an internal session here in Raya about Practical Lightweight Domain Driven Design. This session is truly internal yet. It should be recorded though but I’m not sure whether it’ll be possible to publish the videos (Yeah, I will see how we can have our public sessions of possible sure!). If you have a user group and would like me to give this session in a group meeting, I’ll be glad to do.
Introduction Still: The Messages, The ORM
This post was originally a couple of messages I’ve sent recently to the ALT.NET Yahoo Group . In which I discuss using Domain Driven Design with an ORM, more specifically, my favorite ORM, LLBLGen .
Quoting from the first message:
For now, we're going towards LLBLGen Pro 2.6 for DAL generation and such (using Self-Serving mode probably). Yes, we're going for database first design, and not using NHibrernate. I'm hoping that we can keep those two issues for other threads :).
Right now, I'm going for other Domain Driven practices. I want to make sure using POCO classes is worth it, and then see how to have those in LLBLGen (which -LLBLGen main template- is in its internal not much different design than Active Record, which in many times is handy, it's VERY rare t change DAL when one fits different DB providers with good performance), and what are common patterns to do Domain Driven Design at all when having LLBLGen as DAL (if it makes any difference - again: and if effort to make it encapsulated enough to make no difference is worth it).
Making this choice alone is worth its own article. Maybe should title it “In Search For The Perfect ORM” as well :-D.
UPDATE: Frans Bouma has a nice write-up about what is an ORM and different types on an ORM . It's quite old (2004), but the concepts themselves are still valid.
My original question was:
So, is anybody here doing DDD and uses LLBLGen as DAL generator ?How does the experience look like ? What are common practices across all projects and what have been pitfalls ? etc... These are the kinds of questions I'd love to see somebody here with something to share about.
Domain Driven Design At Work
This is not really an LLBLGen issue. It is questioning the Domain Driven Design productivity itself. I like DDD. I see it as the natural next step after 3-tier deisgn. This whole separation of concerns, models, repositories, factories, infrastructure, and services paradigm just fits my mentality and view of how the world looks like. However, not all the practices in DDD are similar in terms of return of investment, the customer business value that Agile emphasizes. The trick is to know which are and which aren’t, and how to do the balance.
In the second message, I go through an example of typical usage for DDD that has tried just a little bit to be lightweight in some areas but not others, and my own overview about what needs improvement:
I've been on a project that leverages DDD once before myself. The project has been frozen for a while for other priorities, etc...Maybe I start with my own take on the subject!!
We've been using the "Adapter" model. I thought it was for seeking some sort of more control/flexibility. Reading Fran B | Go |
