"Unable to start debugging" - VS2010 ASP.NET MVC 2

Question

I can lunch debug session only once with VS2010 and ASP.NET MVC2. When i end first session and try to lunch another i can see...

"Unable to start debugging" - no other messages, I'm using Visual Studio Development Server instead of IIS, Windows 7 64-bits

I can add that few days ago i was working on Windows XP and everything was fine.

• I've tried running as admin (I thought there are any privilages issues) - no result
• checked http://msdn.microsoft.com/en-us/library/dwesw3ee%28VS.71%29.aspx#vxtbshttpservererrorsthingstocheck (this page refer to IIS settings and i'm not using IIS)
• I'm not satisfied with manually attaching - VS2010 is expensive IDE, it HAVE TO works in this situation

Does anyone have some conclusions?

Answer 1

I've noticed taht if i'll manually stop all WebServers (there are few services which i run locally) i can start debug session...

How can i fix those hanging web servers?? I'm not using IIS, i'm using build-in visual studio 2010 webserver

Answer 2

Noone wanted to help, but problem auto-magically dissapeared when:

1. I've turned off Debug Edit and Continue option
2. Turn on vs2010, run debug.
3. turn off debug, shut down all lunched webServers (i had few of them for different services)
4. Turn off VS2010
5. Turn on VS2010.

After that everything works perfect.
