Hello.
I already asked this question on Stackoverflow here:
http://stackoverflow.com/questions/24359624/visual-studio-2010-it-takes-forever-to-start-web-application/24390849
If I open my web app, then build it and run it (with or without debugger) Visual will be unresponsive for next ~ 30 minutes. After that the app will start and I can build, rebuild and run the same application, normally (no delay anymore).
This seem to happen independently of app size (right now it hang, on nearly empty project). Inside Task Manager, I can see VS is doing something, since memory usage is going up (at the rate of about 100 KB/s).
I tried cleaning everything mentioned on this page:

But nothing helped... what else can I try (besides reinstalling Windows) ?
