The Windows Forms team has been putting together some GREAT sample applications that showcase the power of the new 2.0 engine. If you have the .NET beta available you'll want to check these out. I really like the new toolbar formatters. Way cool.
Joe Stegman did a talk here in Redmond last week about the new Winforms technology. I went to see his presentation. I've done several Smart Client (Windows Forms) talks myself so I wanted to see what was new from Microsoft. As I said: they've put together some real nice samples.
