问题
I can launch debug session only once with VS2010 and ASP.NET MVC2. When I end the first session and try to launch another I can see...
"Unable to start debugging" - no other messages, I'm using Visual Studio Development Server instead of IIS, Windows 7 64-bit
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 privileges issues) - no result
- checked http://msdn.microsoft.com/en-us/library/dwesw3ee%28VS.71%29.aspx#vxtbshttpservererrorsthingstocheck (this page refers to IIS settings and I'm not using IIS)
- I'm not satisfied with manually attaching - VS2010 is expensive IDE, it HAS TO work in this situation
Does anyone have some conclusions?
回答1:
The problem auto-magically disappeared when:
- I've turned off Debug > Edit and Continue option
- Open vs2010 and run debug.
- Turn off debug, shut down all launched WebServers (I had few of them for different services)
- Close VS2010
- Open VS2010.
After that everything works.

A simple restart of VS2010 sorted this for me

I've had this problem twice now and it occurs when I change my password for my computer. I have to go into IIS and change the password on the application pool to match my new password.
回答4:
Also encountered this issue when updated AnkhSVN(I don't believe that updating could cause this problem but I didn't do anything else except code editing).
Closing Development Servers seems solve this issue until next time.
Microsoft Visual Studio 2010 Version 10.0.40219.1 SP1Rel
