I installed the Roslyn CTP, and it worked beatifully for the most part. Then it was time to part with Roslyn, because some features I use aren't implemented yet, and Roslyn replaced the standard compiler. It may be too late for me, but for the afterworld there's still hope:
Is there a way to repair Visual Studio 2010 so it functions like before installing the Roslyn CTP?
Udate: I tried reinstalling Visual Studio 2010 Professional, to no avail. Now I'm investigating the error log, and it says:
CreateInstance failed for package [Roslyn.VisualStudio.VisualBasic.LanguageService.VisualBasicPackage, Roslyn.VisualStudio.VisualBasic, Version=188.8.131.52, Culture=neutral, PublicKeyToken=31bf3856ad364e35]
Is there a setting I can change so Visual Studio uses the old compiler again?
Update 2: There would have been an on/off button in the settings.
Update 3: The on/off button doesn't show. Instead the settings pages for Roslyn stay blank.
Any help is appreciated.
