As Christian mentions in his recent blog post, v0.5 of WSCF (the tool for contract first Web Services development) is now out. This is also accompanied by a very thorough walkthrough of how the tool can be used.
Somewhat coincidentally, I met Christian on Saturday while presenting at TechEd 2005 Academic Days (in a very wet and stormy Orlando). His talk was on various hosting options for .NET, app domains and threading models, which was very well put together. Great job Christian!
