Interface Inheritance Esoterica

ASP.NET MVC — Tue, 10 Nov 2009 18:43:13 GMT

I learned something new yesterday about interface inheritance in .NET as compared to implementation inheritance. To illustrate this difference, here’s a simple demonstration. I’ll start with two concrete classes, one which inherits from the other. Each class defines a property. In this case, we’re dealing with implementation inheritance . public class Person { public string Name { get; set; } } public class SuperHero : Person { public string Alias { get; set; } } We can now use two different techniques to print out the properties of the SuperHero type: type descriptors and reflection. Here’s a little console app that does this. Note the code I’m showing below doesn’t include a few Console.WriteLine calls that I have in the actual app. static...(read more)

Html Encoding Nuggets With ASP.NET MVC 2

ASP.NET MVC — 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)

The Microsoft Ajax Library and Visual Studio Beta 2

Stephen Walther on ASP.NET MVC — Wed, 21 Oct 2009 16:21:39 GMT

Visual Studio 2010 Beta 2 was released this week and one of the first things that I hope you notice is that it no longer contains the latest version of ASP.NET AJAX. What happened? Where did AJAX go? Just like Sting and The Police , just like Phil Collins and Genesis , just like Greg Page and the Wiggles , AJAX has gone out of band! We are starting a solo career. A Name Change First things first. In previous releases, our Ajax framework was named ASP.NET AJAX . We now have changed the name of the framework to the Microsoft Ajax Library . There are two reasons behind this name change. First, the members of the Ajax team got tired of explaining to everyone that our Ajax framework is not tied to the server-side ASP.NET framework. You can use the...(read more)

The Minutes On 9 - Channel 9 Video Interviews with the ASP.NET 4 Team

Scott Hanselman's Computer Zen - ASP.NET MVC — Wed, 21 Oct 2009 07:30:10 GMT

Who loves you? Not only is Visual Studio 2010 Beta 2 now available for everyone to download (not just subscribers) but I've got 11 short video interviews with the ASP.NET 4 team up on Channel 9. I was up in Redmond just last week and made sure to stop by the offices of as many ASP.NET developers and program managers as I could. I chatted with a few faces you may recognize and a few you may not. All of them are working hard to make ASP.NET 4 cool. I'm still working on my video techniques, and I used two different HD cameras to film these videos. Your feedback (negative AND positive) is always appreciated. This series of videos is called Hanselminutes on 9 and you can get to all of these (and many more) using the Channel 9 Tag " hanselminuteson9...(read more)

VS10 Beta 2 From an ASP.NET MVC Perspective

ASP.NET MVC — Wed, 21 Oct 2009 04:30:10 GMT

You probably don’t need me to tell you that Visual Studio 2010 Beta 2 has been released as it’s been blogged to death all over the place. Definitely check out the many blog posts out there if you want more details on what’s included. This post will focus more on what Visual Studio 2010 means to ASP.NET MVC and vice versa. In the box baby! Well one of the first things you’ll notice is that ASP.NET MVC 2 Preview 2 is included in VS10 Beta 2. When you select the File | New menu option, you’ll be greeted with an ASP.NET MVC 2 project template option under the Web node. Note that when you create your ASP.NET MVC 2 project with Visual Studio 2010, you can choose whether you wish to target ASP.NET 3.5 or ASP.NET 4. If you choose to target ASP.NET 4...(read more)

Visual Studio 2010 Beta 2

Scott Hanselman's Computer Zen - ASP.NET MVC — Mon, 19 Oct 2009 16:32:43 GMT

Lots of big stuff happening this week. Today Visual Studio 2010 Beta 2 is available to MSDN Subscribers and it'll be available for everyone on Wednesday. I'm running Beta 2 on all my machines now and really digging it. It's much faster than Beta 1 and I'm doing all my work in it now. It's come a long way and I'm really impressed at the polish. .NET 4 This is a big deal. This isn't ".NET 3.6" - there are a lot of improvements of .NET 4, and it's not just "pile on a bunch of features so you get overwhelmed." I've been working with and talking to many of the teams involved and even though it's a cheesy thing to say, this is a really customer-focused release. Shouldn't every release...(read more)

ASP.NET MVC — Fri, 16 Oct 2009 03:56:02 GMT

A little while ago, Scott Guthrie announced the launch of the Microsoft Ajax CDN . In his post he talked about how ASP.NET 4 will have support for the CDN as well as the list of scripts that are included. The good news today is due to the hard work of Stephen Walther and the ASP.NET Ajax team , they’ve added a couple of new scripts to the CDN which are near and dear to my heart, the ASP.NET MVC 1.0 scripts.

ASP.NET MVC — Thu, 01 Oct 2009 10:00:00 GMT

Today we just released ASP.NET MVC 2 Preview 2 for Visual Studio 2008 SP1 (and ASP.NET 3.5 SP1), which builds on top of the work we did in Preview 1 released two months ago .

Html Encoding Code Blocks With ASP.NET 4

ASP.NET MVC — Fri, 25 Sep 2009 23:56:50 GMT

One great new feature being introduced in ASP.NET 4 is a new code block ( often called a Code Nugget by members of the Visual Web Developer team ) syntax which provides a convenient means to HTML encode output in an ASPX page or view. <% : CodeExpression %> I often tell people it’s <%= but with the = seen from the front. Let’s look at an example of how this might be used in an ASP.NET MVC view. Suppose you have a form which allows the user to submit their first and last name. After submitting the form, the same view is used to display the submitted values. First Name: <% : Model.FirstName %> Last Name: <% : Model.FirstName %> < form method ="post" > <% : Html.TextBox( "FirstName" ) %> <...(read more)

Stephen Walther on ASP.NET MVC — Wed, 16 Sep 2009 20:10:15 GMT

Scott Guthrie announced the launch of the Microsoft Ajax CDN on his blog last night.

There is one more set of JavaScript files that we added to the CDN today that Scott did not announce: the jQuery Validation library. If you are not familiar with the jQuery Validation library then you should know that this is one of the most...(read more)
