A while ago I posted about that I couldn't get intellipad running:
Some days later I tried to start Hanselmans Babysmash, and it totally froze again.
Today, it just hit me when I saw Glenn online. Both apps use MEF.
I downloaded some other big .net apps. Everything runs fine.
Then I ran the MEFlook-Application. It shows up like the screenshot, and then again, the whole VM freezes.
