Krzysztof CwalinaDesigning Reusable FrameworksManaged Extensibility Framework- April 25, 2008 Several months ago we formed what we call Application Framework Core team. The charter of the team is to play the same role in the application frameworks space (WinForms, ASP.NET, WPF, Silverlight) as the Base Class Libraries (BCL) team plays at the bottom of the platform stack. The BCL team did a good job fulfilling the role of the team responsible for decreasing duplication and providing common abstractions for the low levels of the platform. Unfortunately, we did not have a similar team...http://blogs.msdn.com/kcwalina/archive/2008/04/25/MEF.aspx Framework Design Guidelines Digest v2- April 9, 2008 Almost 4 years ago, I blogged about Framework Design Guidelines Digest. At that time, my blog engine did not support attaching files and I did not have a convenient online storage to put the document on, and so I asked people to email me if they want an offline copy. Believe it or not, I still receive 1-2 emails a week with requests for the offline copy. Now that I have a convenient way to put the document online, and the fact that I wanted to make some small updates, I would like to repost...http://blogs.msdn.com/kcwalina/archive/2008/04/09/FDGDigest.aspx Framework Design Studio Released- April 4, 2008 When I was coming back from Mix 2007, I was bored on the plane and so started to write a dev tool. What a geeky thing to do on a plane. :-) The tool allows comparing two versions of an assembly to identify API differences: API additions and removals. Comparing versions of APIs comes very handy during API design process. Often you want to ensure that things did not get removed accidentally (which can cause incompatibilities), and as APIs grow, you want to review the addition without having to...http://blogs.msdn.com/kcwalina/archive/2008/04/04/8357773.aspx Simulated Covariance for .NET Generics- April 2, 2008 I just wrote this pattern, but I am not sure if I should add it officially to the Framework Design Guidelines. It seems like a bit of a corner case scenario, though I do get questions about it from time to time. Anyway, let me know what you think. Different constructed types dont have a common root type. For example, there would not be a common representation of IEnumerable<string> and IEnumerable<object> if not for a pattern implemented by...http://blogs.msdn.com/kcwalina/archive/2008/04/02/SimulatedCovariance.aspx |
