First Guide to MEF & Silverlight (Part–I)

Posted: 14 Aug 2010 04:58 AM PDT

MEF is a framework to extend your application and was introduced in .Net Framework 4.0 and Silverlight 4.0. Recently I got a chance to look around the MEF with Silverlight. I found it useful in various scenarios and thus thought to do something with MEF...( read more )...(read more)

More Versioning Fun With Optional Arguments

Posted: 12 Aug 2010 02:26 PM PDT

In my last blog post , I covered some challenges with versioning methods that differ only by optional parameters. If you haven't read it, go read it. If I do say so myself, it's kind of interesting. ;) In this post, I want to cover another very subtle versioning issue with using optional parameters. At the very end of that last post, I made the following comment. By the way, you can add overloads that have additional required parameters. So in this way, you are in the same boat as before. However, this can lead to subtle bugs. Let's walk through a scenario. Imagine that some class library has the following method in version 1.0. public static void Foo( string s1, string s2, string s3 = "v1" ) { Console.WriteLine( "version 1"...(read more)

The Weekly Source Code 56 - Visual Studio 2010 and .NET Framework 4 Training Kit - Code Contracts, Parallel Framework and COM Interop

Posted: 12 Aug 2010 02:07 AM PDT

Do you like a big pile of source code? Well, there is an imperial buttload of source in the Visual Studio 2010 and .NET Framework 4 Training Kit . It's actually a 178 meg download, which is insane. Perhaps start your download now and get it in the morning when you get up. It's extremely well put together and I say Kudos to the folks that did it. They are better people than I. I like to explore it while watching TV myself and found myself looking through tonight. I checked my blog and while I thought I'd shared this with you before, Dear Reader, I hadn't. My bad, because it's pure gold . With C# and VB, natch. Here's an outline of what's inside. I've heard of folks setting up lunch-time study groups and going through...(read more)

Versioning Issues With Optional Arguments

Posted: 10 Aug 2010 10:32 AM PDT

One nice new feature introduced in C# 4 is support for named and optional arguments . While these two features are often discussed together, they really are orthogonal concepts. Let's look at a quick example of these two concepts at work. Suppose we have a class with one method having the following signature. // v1 public static void Redirect( string url, string protocol = "http" ); This hypothetical library contains a single method that takes in two parameters, a required string url and an optional string protocol . The following shows the six possible ways this method can be called. HttpHelpers.Redirect( "http://haacked.com/" ); HttpHelpers.Redirect(url: "http://haacked.com/" ); HttpHelpers.Redirect( "http...(read more)

How to Post Code To Your Blog and other Religious Arguments

Posted: 09 Aug 2010 05:28 PM PDT

If you've got a programming blog, chances are you'll want to post some code snippets. Posting code sounds easy but it's surprisingly tricky if you consider all the ways that people will be reading your blog. There's a number of ways. Here's a few and their pros and cons . Copy Paste from your IDE (like Visual Studio, for example) If I copy paste directly from VS into my editor of choice, Windows Live Writer, I'll get a <pre> section. using System; namespace WindowsGame1 { #if WINDOWS || XBOX     static class Program     {         /// <summary>         /// The main entry point for the application.        ...(read more)

Optional named parameters work pretty well

Posted: 08 Aug 2010 11:36 PM PDT

Rob has found a use for dynamic: http://blog.wekeroad.com/2010/08/06/flexible-parameters-with-csharp Yay! Let's celebrate! Well, I was a little puzzled because I don't think it quite adds up in the specific example he chose (although please see no aggressiveness here: Rob's a friend; peace!). The idea is to have the same flexibility that a dynamic language can offer in terms of evolution of an API. Here's his original Ruby example: def my_method(args)   thing_one = args["thing1"]   thing_two = args["thing2"] end my_method :thing1 => "value", :thing2 = Time.now The idea, which is quite common in dynamic languages, is that instead of passing a list of predetermined parameters in a specific order, you...(read more)

Orchard 0.5 is out

Posted: 05 Aug 2010 02:53 PM PDT

Before I joined Microsoft seven years ago, I had spent a couple of years building a Web CMS. It wasn't open-source unfortunately but the experience convinced me that most public-facing web sites would shortly use some form of CMS. I also forged strong opinions about the right level of component granularity that a CMS must implement. For the last year and a half, I have been fortunate enough to work with a talented small team within ASP.NET and with a growing community from all around the world on building a new Web CMS on top of ASP.NET MVC. Today I am very happy to invite my readers to check out some of the results of that work: earlier this week, we released version 0.5 of Orchard . We are far from being done, but this is an important milestone...(read more)

Web Farm Framework 2.0 beta released!

Creating Copies of Attributes

Posted: 05 Aug 2010 09:36 AM PDT

I've been working on a lovely little prototype recently but ran into a problem where my code receives a collection of attributes and needs to change them in some way and then pass the changed collection along to another method that consumes the collection. I want to avoid changing the attributes directly, because when you use reflection to retrieve attributes, those attributes may be cached by the framework. So changing an attribute is not a safe operation as you may be changing the attribute for everyone else who tries to retrieve them. What I really wanted to do is create a copy of all these attributes, and pass the collection of copied attributes along. But how do I do that? CustomAttributeData Brad Wilson and David Ebbo to the rescue! In...(read more)

Announcing the OData Helper for WebMatrix Beta
