| ASP.NET MVC Design Gallery and Upcoming View Improvements with the ASP.NET MVC Release Candidate ... Today we launched a new ASP.NET MVC Design Gallery on the www.asp.net site. The design gallery hosts free HTML design templates that you can download and easily use with your ASP.NET MVC applications. Included with each design template is a Site.master file, a CSS stylesheet, and optionally a set of images, partials, and helper methods that support them. The gallery allows you to preview each of the designs online, as well as download a .zip version of them that you can extract and integrate into your site. The gallery allows anyone to create and submit new designs under the creative commons license. Visitors to the gallery can vote to provide feedback on them (thumbs up/thumbs down). The most popular designs show up at the top of the gallery. We think this will provide a useful way for developers to more easily create attractive, standards compliant, sites. It will also hopefully encourage folks to create and share designs that can be easily re-used by others. Upcoming View Improvements with the Release Candidate While on the topic of UI, I thought I'd also share a few details about some of the View-related improvements that are coming with the new ASP.NET MVC Release Candidate (RC) build that will be shipping shortly. In addition to bug fixes, the release candidate incorporates a number of view-specific feature additions and community suggestions. Views without Code-Behind Files Based on feedback from a lot of people, we've decided to make a change so that MVC view files by default do not have code-behind files. This change helps to reinforce the purpose of views in a MVC world (which are intended to be purely about rendering and to not contain any non-rendering related code), and for most people eliminates unused files in the project: With the ASP.NET MVC Beta, developers could eliminate the code-behind file by using the CLR syntax for generic types in a view's inherits attribute , but that CLR syntax is (to put it mildly) pretty undiscoverable and hard to use. The ASP.NET MVC team was able to combine a few extensibility features already in ASP.NET to now enable the standard VB/C# language syntax within the inherits attribute with the ASP.NET RC build: One other nice benefit of not using a code-behind file is that you'll now get immediate intellisense when you first add them to the project. With the beta you had to do a build/compile immediately after creating a view in order to get code intellisense within it. The RC makes the workflow of adding and immediately editing a view compile-free and much more seamless. Top-Level Model Property on Views With previous builds of ASP.NET MVC, you accessed the strongly typed model object passed to the view using the ViewData.Model property: The above syntax still works, although now there is also a top-level "Model" property on ViewPage that you can use: This property does the same thing as the previous code sample - its main benefit is that it allows you to write the code a little more concisely. HTML/AJAX Helpers Now Enable Expression Syntax One of the requests a few people have asked for is the ability to use strongly-typed expression syntax (instead of using strings) when referring to the Model when using a View's HTML and AJAX helper objects. With the beta build of ASP.NET MVC this wasn't possible, since the HtmlHelper and AjaxHelper helper classes didn't expose the model type in their signature, and so people had to build helper methods directly off of the ViewPage<TModel> base class in order to achieve this. The ASP.NET MVC RC build introduces new HtmlHelper<TModel> and AjaxHelper<TModel> types that are exposed on the ViewPage<TModel> base class. These types now allow anyone to build strongly-typed HTML and AJAX helper extensions that use expression syntax to refer to the View's model. For example, I could build a (very simple) strongly-typed "TextBox" helper method using | Go |

| New ASP.NET Charting Control: ... Microsoft recently released a cool new ASP.NET server control - <asp:chart /> - that can be used for free with ASP.NET 3.5 to enable rich browser-based charting scenarios: Download the free Microsoft Chart Controls Download the VS 2008 Tool Support for the Chart Controls Download the Microsoft Chart Controls Samples Download the Microsoft Chart Controls Documentation Visit the Microsoft Chart Control Forum Once installed the <asp:chart/> control shows up under the "Data" tab on the Toolbox, and can be easily declared on any ASP.NET page as a standard server control: <asp:chart /> supports a rich assortment of chart options - including pie, area, range, point, circular, accumulation, data distribution, ajax interactive, doughnut, and more. You can statically declare chart data within the control declaration, or alternatively use data-binding to populate it dynamically. At runtime the server control generates an image (for example a .PNG file) that is referenced from the client HTML of the page using a <img/> element output by the <asp:chart/> control. The server control supports the ability to cache the chart image, as well as save it on disk for persistent scenarios. It does not require any other server software to be installed, and will work with any standard ASP.NET page. To get a sense of how to use the <asp:chart /> control I recommend downloading the Microsoft Chart Controls Sample Project . This includes over 200 ASP.NET sample pages that you can run locally. Just open the web project in VS 2008 and hit run to see them in action - you can then open the .aspx source of each to see how they are implemented. The below example (under Chart Types->Line Charts->3D Line and Curve Charts) demonstrates how to perform Line, Spline and StepLine charting: The below example (under Chart Types->Pie and Doughnut Charts) demonstrates a variety of pie and 3D doughnut options: The below example (under Chart Types->Advanced Financial Charts) demonstrates some graph charts: In addition to the above samples, you can download the Microsoft Chart Control Documentation or ask questions on the Chart Controls Forum to learn more. This should provide a useful (and free) addition to your standard ASP.NET toolkit of functionality, and enable you to easily add richer visualization and data workflow scenarios to your ASP.NET applications. Hope this helps, Scott | Go |
| jQuery Intellisense in VS 2008 ... Last month I blogged about how Microsoft is extending support for jQuery . Over the last few weeks we've been working with the jQuery team to add great jQuery intellisense support within Visual Studio 2008 and Visual Web Developer 2008 Express (which is free). This is now available to download and use. Steps to Enable jQuery Intellisense in VS 2008 To enable intellisense completion for jQuery within VS you'll want to follow three steps: Step 1: Install VS 2008 SP1 VS 2008 SP1 adds richer JavaScript intellisense support to Visual Studio, and adds code completion support for a broad range of JavaScript libraries. You can download VS 2008 SP1 and Visual Web Developer 2008 Express SP1 here . Step 2: Install VS 2008 Patch KB958502 to Support "-vsdoc.js" Intellisense Files Two weeks ago we shipped a patch that you can apply to VS 2008 SP1 and VWD 2008 Express SP1 that causes Visual Studio to check for the presence of an optional "-vsdoc.js" file when a JavaScript library is referenced, and if present to use this to drive the JavaScript intellisense engine. These annotated "-vsdoc.js" files can include XML comments that provide help documentation for JavaScript methods, as well as additional code intellisense hints for dynamic JavaScript signatures that cannot automatically be inferred. You can learn more about this patch here . You can download it for free here . Step 3: Download the jQuery-vsdoc.js file We've worked with the jQuery team to put together a jQuery-vsdoc.js file that provides help comments and support for JavaScript intellisense on chained jQuery selector methods. You can download both jQuery and the jQuery-vsdoc file from the official download page on the jQuery.com site: Save the jquery-vsdoc.js file next to your jquery.js file in your project (and make sure its naming prefix matches the jquery file name): You can then reference the standard jquery file with an html <script/> element like so: Or alternatively reference it using the <asp:scriptmanager/> control, or by adding a /// <reference/> comment at the top of a standalone .js file. When you do this VS will now look for a -vsdoc.js file in the same directory as the script file you are referencing, and if found will use it for help and intellisense. The annotated For example, we could use jQuery to make a JSON based get request, and get intellisense for the method (hanging off of $.): As well as help/intellisense for the $.getJSON() method's parameters: The intellisense will continue to work if you nest a callback function within the method call. For example, we might want to iterate over each JSON object returned from the server: And for each of the items we could execute another nested callback function: We could use the each callback function to dynamically append a new image to a list (the image src attribute will point to the URL of the returned JSON media image): And on each dynamically created image we could wire-up a click event handler so that when it is pressed it will disappear via an animation: Notice how the jQuery intellisense works cleanly at each level of our code. JavaScript Intellisense Tips and Tricks Jeff King from the Web Tools team wrote up a great post earlier this week that answers a number of common questions about how JavaScript intellisense works with VS 2008. I highly recommend reading it. One trick he talks about which I'll show here is a technique you can use when you want to have JavaScript intellisense work within user-controls/partials (.ascx files). Often you don't want to include a JavaScript library <script src=""/> reference within these files, and instead have this live on the master page or content page the user control is used within. The problem of course when you do this is that by default VS has no way of knowing that this script is available within the user control - and so won't provide intellisense of it for you | Go |
| Update on Silverlight 2 - and a glimpse of Silverlight 3 ... We shipped Silverlight 2 last month. Over the last 4 weeks, the final release of Silverlight 2 has been downloaded and installed on more than 100 million consumer machines. It has also recently been published to corporate administrators via the Microsoft SMS and Microsoft Update programs to enable them to automatically deploy across enterprises. Over 1 in 4 computers on the Internet now have some version of Silverlight installed. Silverlight 2 was a major release, and delivered an impressive set of cross-browser, cross-platform functionality for Media and Rich Internet Application experiences. It has been great watching new sites launch using it. Media Experiences Silverlight 2 enables the highest quality video on the web, and delivers it with the lowest TCO of any media platform. One of the capabilities built-into Silverlight 2 is its support for "adaptive streaming" - which enables video to be delivered at multiple bitrates (for example: 400Kbits, 800Kbits, 1.5Mbits, 2Mbits) with Silverlight dynamically choosing the optimal bitrate to use depending on the network bandwidth and CPU capability of the client (it can also automatically switch bitrates seamlessly if conditions change later). Silverlight's adaptive streaming support is extensible. Move Networks (who helped pioneer the concept of adaptive streaming) have already integrated their adaptive streaming solution with Silverlight. Silverlight 2 and Move were used to stream the Democratic National Convention live on the web this summer. Last month we announced that Microsoft will be adding adaptive streaming support as a free feature of our IIS7 web-server. IIS Smooth Streaming will provide an integrated way to deliver HD quality adaptive video over the web. Visit Akamai's www.smoothhd.com site to see some awesome examples of Silverlight 2 and IIS Smooth Streaming in action (with adaptive streaming up to 2.5Mbits). The NBC Olympics site used Silverlight 2 to serve more than 3,500 hours of live and on-demand Olympic coverage to over 60 million unique visitors this summer. Visitors to the site watched an average of 27 minutes of video - which is stunningly high for online video. The site used the new Silverlight adaptive streaming capability to support 1.5Mbit bitrates - which helped deliver an awesome video experience: In addition to powering the Olympics experience in the US, Silverlight was also used in France (by FranceTV ), the Netherlands (by NOS ), Russia (by Sportbox.ru ) and Italy (by RAI ). In addition to video quality, a big reason behind these broadcasters decision to use Silverlight was the TCO and streaming cost difference Silverlight provided. In the August 2008 edition of Web Designer Magazine (a Dutch publication) a NOS representative reported that they were able to serve 100,000 concurrent users using Silverlight and 40 Windows Media Servers, whereas it would have required 270 servers if they had used Flash Media Servers. Over the last month we've seen several major new deployments of Silverlight for media scenarios. For example: CBS College Sports is now using Silverlight to stream NCAA events from its 170 partner colleges and university. Blockbuster is replacing Flash with Silverlight for its MovieLink application. And Netflix two weeks ago rolled out its new Instant Watch service using Silverlight. Rich Internet Applications (RIA) Experiences Silverlight 2 delivers a cross-browser, cross-platform subset of the .NET Framework, and enables developers to build Rich Internet Applications. Developers can use either VS 2008 or the free Visual Web Developer 2008 Express to open and edit Silverlight 2 projects, and get a powerful code-focused .NET development environment. Designers can use Expression Blend 2 SP1 to open and edit the same projects and use a creative tool to sculpt and create rich user experiences. I recently blogged about the nice dev | Go |
| Styling a Silverlight Twitter Application with Expression Blend 2 ... Silverlight 2 provides a rich platform for building cross-browser/cross-platform RIA applications. One of the things that makes Silverlight so powerful is the ease with which developers and designers can collaborate together on projects. Developers can use Visual Studio to open and edit Silverlight 2 projects and get a powerful code-focused .NET development environment, and designers can use Expression Blend 2 SP1 to open and edit the exact same project and use a creative tool to sculpt and create optimal user experience designs. The WPF UI framework shipped in Silverlight further enables a great designer/developer workflow by supporting concepts like layout management, controls, styles, templates, and resources - which help avoid scenarios where designers and developers end up tripping over each other when integrating functionality, behavior and expressive design. Silverlight 2 Twitter Sample Last month I posted an in-depth blog tutorial on how to build a Silverlight 2 Digg application which you can read here . This tutorial was aimed primarily at developers, and focused on introducing the fundamental programming concepts involved when building a Silverlight 2 application. Today Celso Gomes and Peter Blois posted a cool 10 minute video tutorial that shows off using Expression Blend to stylize a Silverlight 2 Twitter Messenger application. You can watch the video here . You can download the source code for the completed Silverlight Twitter application here . The video does a nice job demonstrating how designers can re-style a Silverlight application without having to mess with the code behind it. In the process it shows some of the power and capability that Expression Blend 2 provides to build really rich user experiences. Celso starts with a developer version of the application, and then customizes and sculpts the UI to have a fun twitter character theme: The Application Model The Silverlight Twitter client is hosted within an ASP.NET server application that exposes a web service that enables the Silverlight Twitter application to communicate to the Twitter service (since Twitter does not allow direct access from client applications). Communication between the Silverlight client and the ASP.NET web server is done using Windows Communication Foundation (WCF). The client application uses a Model-View-Presenter (MVP) pattern (also known as the Model-View-ViewModel pattern) which is commonly used in large WPF applications. Even though this is a fairly simple application they wanted to take advantage of the flexibility that MVP allows and allow room for future growth. Maintaining the separation between the visuals and the application logic also enables designers to make fairly complex visual changes without impacting the basic application flow. The video goes through some examples of the styling flexibility this architecture facilitates. The Styling Process In the video, Celso highlights how Resources can help designers quickly change colors. A common Brush Resource, for example, can be used to change the color of all the text elements in the application: Celso shows how easy is to create new User Controls from graphics using Expression Blend 2 SP1 (just select multiple elements in the designer, right-click, and choose the "Make Control" menu option): And also how to create new states inside this new User Control (using the Visual State Manager feature - which is also now supported with WPF), to animate the bird (fly, blink, etc...) Celso also shows how to create animations for each state, changing advanced properties like Key Spline curves, and Repeat Behavior: He also shows how to create custom buttons from drawings (which can come from XAML or any other design tool like Photoshop or Illustrator). All the states of a Button Control are available out of the box. Expression Blend also enables you to easily change complex controls like List Boxes. Designers have acce | Go |
| Nov 6th Links: ASP.NET, ASP.NET AJAX, jQuery, ASP.NET MVC, Silverlight and WPF ... Last week was our big PDC conference, and I've been busy catching up back at work this week. I'm hoping to publish a bunch of new posts soon (including some on the PDC announcements we made). Until then, here is the latest in my link-listing series . 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 6 New ASP.NET Dynamic Data Videos : Joe Stagner has just published 6 new videos on the www.asp.net site that cover how to use the cool new ASP.NET Dynamic Data functionality introduced with .NET 3.5 SP1. Download Hotfix: False C# Compilation Errors for ASP.NET Code Behind Files with VS 2008 SP1 : The C# team added support for live semantic errors with background compilation in VS 2008 SP1. There were a few cases where this caused false errors to be shown with ASP.NET Web site projects. You can fix these either by disabling live semantic errors (tools->options allows you to disable this), or by downloading a recent hotfix patch which is now public. Omar Khan has a useful blog post with more details on it. Examining ASP.NET 2.0's Membership, Roles and Profile - Part 13 : Scott Mitchell has another post in his great series of ASP.NET security articles. This one covers how to create a login screen that allows admin users to log in as another user in the user database. For more on ASP.NET security, also check out Joe Stagner's recent ASP.NET Security Videos . ASP.NET Patterns Developers Should Know : Alex Homer from the Patterns and Practices (PAG) team at Microsoft has a nice article that introduces a number of common design patterns (MVC and MVP, Repository, Singleton, etc) and how you can apply them within ASP.NET applications.

| ASP.NET MVC Beta Released ... Today we released a beta of the new ASP.NET MVC framework. Click here to download it. You can also visit www.asp.net/mvc to explore tutorials , quickstarts , and videos to learn more. The ASP.NET MVC Beta works with both .NET 3.5 and .NET 3.5 SP1, and supports both VS 2008 and Visual Web Developer 2008 Express SP1 (which is free - and now supports class libraries and web application project types). Today's ASP.NET MVC Beta release comes with an explicit "go-live" license that allows you to deploy it in production environments. The previous preview releases also allowed go-live deployments, but did so by not denying permission to deploy as opposed to explicitly granting it (which was a common source of confusion). Today's release is clearer about this in the license. The beta release is getting close to V1 feature complete, although there are still a few more features that will be added before the final "V1" release (including several VS tooling enhancements). The team decided to call this release a "beta", though, because the quality and testing of it is higher than the previous previews (a lot of bug fixes and performance tuning work went into it), and they feel that the core features that are in it are now "baked enough" that there won't be major changes from this release to the final product. This post contains a quick summary of some of the new features and changes in this build compared to the previous "Preview 5" release: New "Add View" Menu in Visual Studio New \Scripts directory and jQuery Support Built-in Model Binder Support for Complex Types Refactored Model Binder Infrastructure Strongly Typed UpdateModel and TryUpdateModel WhiteList Filtering Improved Unit Testing of UpdateModel and TryUpdateModel Scenarios Strongly Typed [AcceptVerbs] attribute Better Validation Error Messages HTML Helper Cleanup and Refactoring Silverlight / ASP.NET MVC Project Integration ASP.NET MVC Futures Assembly \Bin and GAC Assembly Deployment I am also planning to publish a few end to end tutorials in the weeks ahead that explain ASP.NET MVC concepts in more depth for folks who have not looked at it before, and who want a "from the beginning" set of tutorials on how to get started. New "Add View" Menu in Visual Studio With previous ASP.NET MVC preview releases you had to manually add views through the Project->Add New Item dialog in VS, and creating and wiring up everything required several manual steps (making sure the directory/file structure is right, going into the code-behind file to specify the strongly typed ViewData model type, etc). Today's beta makes the steps much easier. You can now just move your source editor cursor to be within a Controller action method in the source editor, and then right-click and select a new "Add View" context menu item (alternatively you can type the Ctrl-M Ctrl-V keyboard shortcut to invoke this without having to take your hands off the keyboard): This will bring up a new "Add View" dialog that allows you to specify the name of the view you want to create, its master page, and optionally its strongly typed ViewData "Model" type: Visual Studio will automatically pre-populate the view name based on the action method your cursor is within (you can then override this if you want). For example, if our cursor had been within an "Edit" action method when we selected "add view" it would have pre-populated the view name textbox with "Edit" instead of "Browse". The strongly typed ViewData "model" for a view can be selected from an editable ComboBox that lists all classes in (or referenced) from the MVC project: You can either select a type from the list, or manually type one in the ComboBox. You can also optionally pick an initial type from the list and then tweak it. For example, we could select the "Product" class from the list and then use the ComboBox editing support to wrap it as an IEnumerable<Product> - meaning a sequence of pr | Go |
| Silverlight 2 Released ... Today we shipped the final release of Silverlight 2. You can download Silverlight 2, as well the Visual Studio 2008 and Expression Blend 2 tool support to target it, here . Cross Platform / Cross Browser .NET Development Silverlight 2 is a cross-platform browser plugin that enables rich media experiences and .NET RIAs (Rich Internet Applications) within the browser. Silverlight 2 is small in size (4.6MB) and takes only 4-10 seconds to install on a machine that doesn't already have it. It does not require the .NET Framework to be installed on a computer to run - the Silverlight setup download includes everything necessary to play video or run applications. Developers can write Silverlight applications using any .NET language (including VB, C#, JavaScript, IronPython and IronRuby). Silverlight provides a rich set of features for development including: WPF UI Framework : Silverlight 2 includes a rich UI framework that makes building rich Web applications much easier. In includes a powerful graphics and animation engine, as well as rich support for higher-level UI capabilities like controls, layout management, data-binding, styles, and template skinning. The WPF UI Framework in Silverlight is a compatible subset of the WPF UI Framework features in the full .NET Framework, and enables developers to re-use skills, controls, code and content to build both rich cross browser web applications, as well as rich desktop Windows applications. Rich Controls : Silverlight 2 includes a rich set of built-in controls that developers and designers can use to quickly build applications. The Silverlight 2 release includes core form controls (TextBox, CheckBox, RadioButton, ComboBox, etc), built-in layout management panels (StackPanel, Grid, Panel, etc), common functionality controls (Slider, ScrollViewer, Calendar, DatePicker, etc), and data manipulation controls (DataGrid, ListBox, etc). All Silverlight controls support a rich control templating model, which enables developers and designers to collaborate together to build highly polished solutions. Rich Networking Support : Silverlight 2 includes rich networking support. It includes out of the box support for calling REST, WS*/SOAP, POX, RSS, and standard HTTP services. It supports cross domain network access (enabling Silverlight clients to directly access resources and data from resources on the web). It also includes built-in sockets networking support. Rich Base Class Library : Silverlight 2 includes a rich .NET base class library of functionality (collections, IO, generics, threading, globalization, XML, local storage, etc). It includes rich APIs that enable HTML DOM/JavaScript integration with .NET code. It includes LINQ and LINQ to XML library support (enabling easy transformation and querying of data), as well as local data caching and storage support. The .NET APIs in Silverlight are a compatible subset of the full .NET Framework. Rich Media Support : Silverlight 2 includes built-in video codecs for playing high definition video, as well as for streaming it over the web (including both live and on-demand support). Silverlight includes support for adaptively switching video bitrates on the fly based on network conditions (enabling users to avoid seeing the dreaded "buffering..." message), placing and metering ads within video streams, as well as enabling content protection. The final Silverlight 2 release delivers a tremendous amount of power and flexibility that enables you to really push the boundaries of what can be done in a browser, and enable great end user experiences. Silverlight Customers Over the last few months a number of very high profile sites have successfully launched using the beta releases of Silverlight 2. In August, NBC hosted the Olympics live on nbcolympics.com and served up 1.3 billion page views, 70 million video streams, and 600 million minutes of video content - makin | Go |

| 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.

| Apply ASP.NET Authentication and Authorization Rules to Static Content with IIS 7.0`s Integrated Pipeline Feature ... Many ASP.NET applications that support user accounts use forms-based authentication and URL authorization . Forms-based authentication
is a mechanism by which users can log into the site by entering their credentials - typically a username and password - into textboxes in a login page.
Once validated, the server returns an authentication ticket cookie that identifies the request; this cookie is sent back on subsequent visits
to the site, which keeps the user "logged on" for the lifetime of the cookie or until the authentication ticket expires. URL authorization is a mechanism
by which authorization rules can be defined on a URL-by-URL or folder-by-folder basis. In short, with URL authorization you can instruct the application
to deny access to a particular folder to anonymous users, or prohibit access to a particular URL to all users except those in the Admin role.
Because the forms-based authentication and URL authorization features are part of ASP.NET, the ASP.NET runtime must be consulted in order for these
features to be employed. When developing an application using Visual Studio and the ASP.NET Development Server, all requests are handed off to
the ASP.NET runtime. Consequently, the authentication and authorization logic applies to both ASP.NET-specific content like ASP.NET pages and
Web Services, as well as static content like images, PDFs, and ZIP files. Things are a bit different with IIS ,
Microsoft's production-grade web server software. By default, IIS handles all static content itself, only invoking the ASP.NET runtime when an
ASP.NET resource is requested. As a result, those URL authorization rules you apply to static content are ignored when hosting your site in a production
environment!
The good news is that starting with IIS 7.0 Microsoft has introduced the integrated pipeline . In a nutshell, with the integrated pipeline you
can instruct IIS to work with the ASP.NET runtime during the processing of all requests, regardless of whether the request is for an ASP.NET-specific
resource. This article shows how to use the integrated pipeline feature to apply ASP.NET forms-based authentication and URL authorization rules to
static content. Read on to learn more!

| ASP.NET Providers with Windows Azure ... Are you trying to get the ASP.NET Provider code working in a
separate application with Windows Azure? If so, check out this item
from the read me file: Make sure that the Table Storage
service is running in development storage. Also make sure that the
database called 'ServiceHostingSDKSamples' is currently selected for
the table service; choose Development Storage -> Tools -> Table
service properties -> ServiceHostingSDKSamples. I missed this and got the error message below: <?xml version=\"1.0\" encoding=\"utf-8\" standalone=\"yes\"?> <error xmlns=\"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata\"> <code></code> <message xml:lang=\"en-US\">Attempt to create table 'Sessions' failed. Creating a new table dynamically is not supported in development storage </message> </error> I
sure hope that this changes in the future. I'd like some way to have
the asp.net membership "stuff" setup for me, like with .net 2.x. | Go |
| Strongly typed workflow input and output arguments ... When you run a Workflow using Workflow Foundation, you pass arguments to the workflow in a Dictionary form where the type of Dictionary is Dictionary<string, object> . This means you miss the strong typing features of .NET languages. You have to know what arguments the workflow expects by looking at the Workflow public properties. Moreover, there’s no way to make arguments required. You pass parameter, expect it to run, if it throws exception, you pass more arguments, hope it works now. Similarly, if you are running workflow synchronously using ManualWorkflowSchedulerService , you expect return arguments from the Workflow immediately, but there again, you have to rely on the Dictionary key and value pair. No strong typing there as well. In order to solve this, so that you could pass Workflow arguments as strongly typed classes, you can establish a format that every Workflow has only two arguments named "Request” and “Response” and none other. Whatever needs to be passed to the Workflow and expected out of it, must be passed via Request and must be expected via Response properties. Now the type of these arguments can be workflow specific, it can be any class with one or more parameters. This way, you could write code like this: The advantages of these strongly typed approach are: Compile time validation of input parameters passed to workflow. No risk of passing unexpected object in Dictionary’s object type value. Enforce required values by creating Request objects with non-default constructor. Establish a fixed contract for Workflow input and output via the strongly typed Request and Response classes or interfaces. Validate input arguments for the Workflow directly from the Request class, without going through the overhead of running a workflow. If we follow this approach, we create workflows with only two DependencyProperty , one for Request and one for Response . Showing you an example from my open source project Dropthings , which uses Workflow for the entire Business Layer. Below you see the Workflow that executes when a new user visits Dropthings.com , creates a new user and setups all the pages and widgets for the user. It has only two Dependency property – Request and Response. The Request parameters is of type IUserVisitWorkflowRequest . So, you can pass any class as Request argument that implements the interface. Here I have used fancy inheritance to create Request object hierarchy. You don’t need to do that. Just remember, you can pass any class. You don’t even need to use interface for Request parameter. It can be a class directly. I use all these interfaces in order to facilitate Dependency Inversion. Similarly, the Response object is also a class. The Response returns quite some properties. So, it’s kinda handy to wrap them all in one property. So, there you have it, strongly typed Workflow arguments. You can attach properties of the Request object to any activity directly form the designer: There’s really no compromise to make in this approach. Everything works as before. In order to make workflow execution simpler, I use a helper method like the following, that takes the Request and Response object and creates the Dictionary for me. This Dictionary always contains one “Request” and one “Response” entry. This way, I can run Workflow in strongly typed fashion: Here I can specify the Request, Response and Workflow type using strong typing. This way I get strongly typed return object as well as pass strongly type Request object. There’s no dictionary building, no risky string key and object type value passing. You can ignore the ObjectContainer.Resolve() stuff, because that’s just returning me an existing reference of WorkflowRuntime . Hope you like this approach. var dzone_url = 'http://weblogs.asp.net/omarzabir/archive/2008/12/27/strongly-typed-workflow-input-and-output-arguments.aspx'; var dzone_title = 'Strongly typed workflow input and output arguments'; var dzone_blurb = 'Strongly typed workflow inp | Go |

| Continuous Integration (book) ... First my personal impression - this book is a very good "business case" to introduce things like automated builds, CI server, DB continuous integration (loved the word CDBI), automated deployment, automated inspection - most of the things that CI leverages. It doesn't go into deep details of one or another particular technology, balancing most of examples between (mostly) Java and .NET worlds. From my personal experience, if your company doesn't practice CI in any shape or form and shows no interest in it, using excuses like "we deploy internally", "our deployment consist of a few assemblies and content files", or worse "there's no real benefit in it" - think twice if you are in the right place and do your math. CI is simple to start, it's free, and most of all, ROI is guaranteed. | Go |

| Some interesting things I am finding about Windows Azure ... Queue messages have a max size of 8kb.
Queued messages in azure are typed.
If you are interested in #Azure, I would suggest following @smarx on twitter.com.
Transaction support will come in future #Azure CTPs.
ACID Transactions are only supported on single entity updates at this time in azure.
Azure table writes are synchronous.
In the commercial release, MS will offer some control over geodistribution and georeplication. Info is scarce at this time.
In the CTP, Azure runs in "a single datacenter on the US west coast."
The lease timeframe appears to be configurable. The default is 30 seconds.
You can hold a lease on message in an azure queue. No one else can see it during the lease. This is good.
These are just some of the things I have found while reading online. As I find out more, I'll be posting. If you want immediate access to my info, go to twitter.com and follow me (@wbm) | Go |
