ASP.NET 4 / VS 2010 “Quick Hit” Videos

Misfit Geek: msft — Mon, 09 Nov 2009 13:49:13 GMT

Now that the “Dev 2010” wave of products is in beta and we’re getting closer5 and closer to release, I‘ve started publishing “Quick Hit” videos on the new features. These are not really tutorials (Not like the How-Do-I videos) but rather just “quick” peeks to show you the new stuff. I’ll start working on more detailed training after PDC. The first 5 videos are now live: http://www.asp.net/learn/aspnet-4-quick-hit-videos/ #1 | ASP.NET 4 "Quick Hit" - Chart Control #2 | ASP.NET 4 "Quick Hit" - Dynamic Metadata #3 | ASP.NET 4 "Quick Hit" - Permanent Redirect #4 | ASP.NET 4 "Quick Hit" - Imperative WebForms Routing http://www.asp.net/learn/vs2010-quick-hit-videos/ #1 | Visual Studio 2010 "Quick...(read more)

Neat VS10 Feature: Pinning A Debugger Watch

you've been HAACKED — Sat, 07 Nov 2009 00:42:53 GMT

I was stepping through some code in a debugger today and noticed a neat little feature of Visual Studio 2010 that I hadn’t noticed before. When debugging, you can easily examine the value of a variably by highlighting it with your mouse. Nothing new there. But then I noticed a little pin next to it, which I’ve never seen before. So what do you see when you see a pin? You click on it! As you might expect, that pins the quick watch in place. So now I hit the play button, continue running my app in the debugger, and the next time I hit that breakpoint: I can clearly see the value changed since the last time. I think this may come in useful when walking through code as a way of seeing the value of important variables right next to where they are...(read more)

Recap of Oredev and some .net debugging videos

If broken it is, fix it you should : ASP.NET — Fri, 06 Nov 2009 14:21:00 GMT

This week I attended and spoke at the Oredev conference in Malmö Sweden, and it was great fun as usual. It was a pretty productive few days with a lot of good talks and conversations with some really cool people. I’ll put up a link to the talk as it becomes available Channel9 video and chat with Scott Hanselman for Hanselminutes I got to meet “The man, the myth, the legend” Scott Hanselman and he recorded a 10 minute demo for Channel9 where I showed him how to debug a .Net performance issue using Memory dumps in Visual Studio .NET 2010 Beta 2. http://www.hanselman.com/blog/HanselminutesOn9DebuggingCrashDumpsWithTessFerrandezAndVS2010.aspx We also had a really nice chat about debugging (kind of a 101 primer) for hanselminutes that should be out...(read more)

A RouteHandler for IHttpHandlers

you've been HAACKED — Thu, 05 Nov 2009 00:18:30 GMT

I saw a bug on Connect today in which someone offers the suggestion that the PageRouteHandler (new in ASP.NET 4) should handle IHttpHandler as well as Page . I don’t really agree with the suggestion because while a Page is an IHttpHandler , an IHttpHandler is not a Page . What I this person really wants is a new handler specifically for http handlers. Let’s give it the tongue twisting name: IHttpHandlerRouteHandler . Unfortunately, it’s too late to add this for ASP.NET 4, but it turns out such a thing is trivially easy to write. In fact, here it is. public class HttpHandlerRouteHandler<THandler> : IRouteHandler where THandler : IHttpHandler, new () { public IHttpHandler GetHttpHandler(RequestContext requestContext) { return new THandler...(read more)

Html Encoding Nuggets With ASP.NET MVC 2

you've been HAACKED — Wed, 04 Nov 2009 05:56:49 GMT

In a recent blog post, I introduced ASP.NET 4’s new HTML Encoding code block syntax as well as the corresponding IHtmlString interface and HtmlString class. I also mentioned that ASP.NET MVC 2 would support this new syntax when running on ASP.NET 4 . In fact, you can try it out now by downloading and installing Visual Studio 2010 Beta 2. I’ve also mentioned in the past that we are not conditionally compiling ASP.NET MVC 2 for each platform. Instead, we’re building System.Web.Mvc.dll against ASP.NET 3.5 SP1 and simply including that one in VS08 and VS10. Thus when you’re running ASP.NET MVC 2 on ASP.NET 4, it’s the same byte for byte assembly as the same one you would run on ASP.NET 3.5 SP1. This fact ought to raise a question in your mind. If...(read more)

VS 2010 Beta 2 Read Me Items for Web Deployment

Vishal Joshi's Tangent — Sun, 01 Nov 2009 03:31:00 GMT

There are some known issues/bugs related to VS 2010 Web Deployment features in VS 2010 Beta 2 Read Me… I can imagine reading the entire Beta 2 read me file can be daunting so I thought I can just copy paste the ones related to Web Deployment here… DB Deployment will fail if the Database Name is longer than 127 characters Description: If you are using latest VS 2010 Web Deployment Features and trying to deploy your database using the Deploy SQL property page then at times you might get error from VSMsDeploy task. There might be several reasons for the failure including connection and authentication issue but a current bug in the product does not allow you to script schema/data from a database (typically SQL Express MDF file) if the file...(read more)

JavaScript class browser: once again with jQuery

Tales from the Evil Empire : ASP.NET — 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)

Converting a Web Site Project to a Web Application Project

Visual Web Developer Team Blog — Thu, 29 Oct 2009 23:49:00 GMT

Differences between Web Site Projects (WSP) and Web Application Projects (WAP) are highlighted in blogs such as this one . Based on that, if you feel a WAP would be better for your particular needs than a WSP, but have already created a WSP, you may be asking yourself, “Can I convert my WSP into a WAP, without starting from scratch?”. This posting explains how to convert an existing Web Site Project to a Web Application Project in Visual Studio 2010. The most striking differences to a Web Site Project are that WAPs have a project file to include and exclude files, and compile to a single assembly. The guidelines below include several of the basic steps detailed in the Walkthrough: Converting a Web Site Project to a Web Application Project in...(read more)

Using C# Dynamic to simplify ADO.NET Data Access

Angle Bracket Percent : ASP.NET — Thu, 29 Oct 2009 23:05:00 GMT

Recently, I started playing around with C# dynamic, and blogged how it could be used to call static class members late bound . Today, I was talking to Phil Haack , who I think had talked to ScottGu , and he mentioned that it would be cool to use dynamic to simplify data access when you work directly with SQL query. So I thought I’d play around with that, and it didn’t take much code to make it work nicely. So the scenario is that you’re not using any fancy O/R mapper like LINQ to SQL or Entity Framework, but you’re directly using ADO.NET to execute raw SQL commands. It’s not something that I would personally do, but there are a lot of folks who prefer this over the higher level data access layers. So let’s look at an example...(read more)
