RIA Services: Jumpstarting RIA Development

Nikhil Kothari's Weblog — Thu, 19 Nov 2009 09:03:31 GMT

In my post on RIA Services: From Vision to Architecture , a while back (right after MIX09), I mentioned that I like to think of RIA Services as RAD for RIA. At that point we had a very early preview of framework bits with little tools support. A large part of jumpstarting your development actually centers around good tooling. VS2010 brings tooling for RIA Services (now: WCF RIA Services). Scott Hanselman demonstrated some key features used in building a Contacts application (as shown on the right) during the keynote at PDC09 . The latest version of RIA Services is now available for download. It works on .NET 4 and VS2010 as well. You can also check out a video tutorial on using RIA Services and Visual Studio 2010. In this post, I want to highlight...(read more)

re: Visual Studio patched for better jQuery IntelliSense

@KiT: yes, the speed is not optimal in 2008 (although still very usable imo). In VS 2010, you don't even feel it, it's immediate. And much better as well, it does amazing things. Read More......(read more)

JavaScript class browser: once again with jQuery

Tales from the Evil Empire : Microsoft AJAX Library — Fri, 30 Oct 2009 17:43:26 GMT

I’ve already posted twice about that little class browser application. The first iteration was mostly declarative and can be found here: http://weblogs.asp.net/bleroy/archive/2009/09/14/building-a-class-browser-with-microsoft-ajax-4-0-preview-5.aspx The second one was entirely imperative and can be found here: http://weblogs.asp.net/bleroy/archive/2009/10/15/entirely-unobtrusive-and-imperative-templates-with-microsoft-ajax-4-preview-6.aspx This new version builds on top of the code for the imperative version and adds the jQuery dependency in an attempt to make the code leaner and simpler. I invite you to refer to the imperative code (included in the archive for this post ) and compare it with the jQuery version, which shows a couple of ways...(read more)

How to render the same template on the server and client with minimal redundancy

Tales from the Evil Empire : Microsoft AJAX Library — Mon, 19 Oct 2009 08:50:00 GMT

Last week, I wrote a post about how the new Microsoft Ajax Library Preview 6 made it a lot easier to write unobtrusive and imperative data-driven applications . Because for the previous preview, I had written a cool little class browser using a declarative style, I thought it would be nice to rewrite this in a completely imperative way. The mistake I made though was to call it unobtrusive. Never mind that ‘unobtrusive’ is a perfectly well-defined word that actually existed way before JavaScript. ‘Unobtrusive JavaScript’ has a very specific meaning that people feel strongly about. To be worthy of that label, an application must basically conform to (at least) those two requirements: Markup and behavior are strictly separated. That means no DOM...(read more)

Announcing Microsoft Ajax Library (Preview 6) and the Microsoft Ajax Minifier

ScottGu's Blog : Atlas — Fri, 16 Oct 2009 06:48:09 GMT

The ASP.NET team today released a significant new update of the Microsoft Ajax Library (Preview 6). This update includes a bunch of new capabilities and improvements to our client-side AJAX library, and can be used with any version of ASP.NET (including ASP.NET 2.0, 3.5 and 4.0), and can be used in both ASP.NET Web Forms and ASP.NET MVC projects. Today’s release includes the following feature improvements: Better Imperative Syntax : A new, simplified, code syntax for creating client controls. Client Script Loader : A new client-side script loader that can dynamically load all of the JavaScript files required by a client control or library automatically, and executes the scripts in the right order. Better jQuery Integration : All...(read more)

Entirely unobtrusive and imperative templates with Microsoft Ajax Library Preview 6

Tales from the Evil Empire : Microsoft AJAX Library — Thu, 15 Oct 2009 09:12:00 GMT

Today is the release of the sixth preview of Microsoft Ajax Library. Don’t get fooled by the somewhat silly and long name: this is a major release in many ways. The scripts have been majorly refactored since preview 5. Check out the other posts out there (links at the bottom of this post) to see just some of the many new features that are in there. Some of my favorite are all the small improvements that have been made to make imperative instantiation of components and templated contents easier than ever. Many of you have told us that you preferred to do things imperatively and this release makes it a lot better. When Preview 5 came out, I built a simple class browser using the declarative syntax. The class browser shows the hierarchy of namespaces...(read more)

Ajax Control Toolkit: new controls, bug fixes

Tales from the Evil Empire : Microsoft AJAX Library — Thu, 01 Oct 2009 00:28:59 GMT

And we have a new release of Ajax Control Toolkit. I didn’t work on this one but there are some nice things in there nonetheless :) First, new controls! SeaDragon : I’ve blogged before about Seadragon , the JavaScript-only way to do Deep Zoom . It became a lot easier to use a few month ago when the need for tools disappeared and you can just point to any image on the web and immediately get the URL and script tag to put on your page: Now with this release of Ajax Control Toolkit, including and controlling Deep Zoom from an ASP.NET page is also very easy : < ajaxToolkit : Seadragon ID ="Seadragon" CssClass ="seadragon" runat ="server" SourceUrl ="sample.xml"/> James Senior just released a screencast...(read more)

Fluent API for .NET RIA Services Metadata

Nikhil Kothari's Weblog — Mon, 21 Sep 2009 04:34:10 GMT

.NET RIA Services relies heavily on metadata annotations for expressing intent beyond what can be inferrd via convention. For example, validation rules on entities and members can be declared as annotations, which then enable a variety of consumption scenarios. We also have metadata for describing model aspects in DAL-agnostic fashion, and hints for automatic UI-generation. What we have today is just a first step. The general design we're enabling is actually quite flexible. For example, a number of developers want to have metadata specified external to their code, for example in XML files or in a database. Some don't like attributes, and have asked for a fluent interface instead. In RIA Services, we wanted to create a consistent API...(read more)

Announcing the Microsoft AJAX CDN

ScottGu's Blog : Atlas — Wed, 16 Sep 2009 06:46:17 GMT

Earlier today the ASP.NET team launched a new Microsoft Ajax CDN (Content Delivery Network) service that provides caching support for AJAX libraries (including jQuery and ASP.NET AJAX). The service is available for free, does not require any registration, and can be used for both commercial and non-commercial purposes. What does a CDN provide? Content delivery networks (CDNs) are composed of "edge cache" servers that are strategically placed around the world at key Internet network points. These "edge cache" servers can be used to cache and deliver all types of content – including images, videos, CSS and JavaScript files. Using a CDN can significantly improve a website's end-user performance, since it enables...(read more)

Building a class browser with Microsoft Ajax 4.0 Preview 5

Tales from the Evil Empire : Microsoft AJAX Library — Mon, 14 Sep 2009 07:29:37 GMT

The Microsoft Ajax Library 4.0 Preview 5 is the first release of Microsoft Ajax that I didn’t participate in: I left the team a few months ago. But that doesn’t mean I don’t love what’s in there, and I really do. And by the way I’ve also seen what’s in Preview 6 too and man that will seriously rock. So I thought I’d write a little something to celebrate the new preview. The new features include recursive templates, which is pretty much begging us to implement a treeview with it, and we’ll do just that in this post. There is also an intriguing capability, which enables you to dynamically set what template to render for each data item, and where to render it. At first, this doesn’t look like the most useful thing in the world, but it actually...(read more)
