A couple of months ago, after I had just installed the then-new Visual Studio 2005 Beta 2, I could not run any project in the IDE, as it would crash VS. Then I found a workaround using a Visual Studio community feature that I built for MSDN Forums:

Uncheck Tools->Options->Debugger->Redirect all console output to the Quick Console Window

You could also remove the old interop assembly:

rmdir /s /q %windir%\assembly\GAC_MSIL\Microsoft.VisualStudio.Debugger.Interop\

The new one will still be installed in 'assembly\GAC', so you should be good.

 

This workaround came from:

You too can help yourself like I did, while in the Visual Studio 2005 IDE! Use the main menu to select “Community”, and then “Ask a Question”. This feature searches the MSDN Forums to find postings with the keywords you enter. For this feature, I developed a full component stack: SQL stored procedures, a .NET Web Service on top of that, a .NET class library on top of that, and the “Ask a Question” ASP.NET UI on top of that. Another way to search MSDN Forums is use their search UI.

Help me, help you. :)
