Wednesday I installed Visual Studio 2010 Premium, and played a while with the WPF-based editor.
Annoying thing: I could not select any of the controls on a WPF-Application-Form. Whenever I clicked on the TextBox, the Designer added a Border-Control.

I do not know, why this happend, but now I can choose the controls on a form again.
One more nasty thing: Intellisense was disabled for C#. I had to turn it on manually …
