Visual Studio 2010 Extension Manager will work

Question

After installing a bunch of extensions for testing, I restarted VS 2010 and it started to crash. Unfortunately, when opening Tools | Extension manager. Any ideas for fixing and fixing a complete uninstall / reinstall?

The event log has the following: Application: devenv.exe Framework Version: v4.0.30319 Description: The process was aborted due to an unhandled exception. Exception Information: System.AggregateException Stack: at System.Threading.Tasks.TaskExceptionHolder.Finalize ()

Answer 1

Try using safemode

> devenv.exe /SafeMode 

This will start Visual Studio with add-ons / extensions disabled.

Answer 2

Try renaming the folder containing the extensions (and thus temporarily delete them).

 %LOCALAPPDATA%\Microsoft\VisualStudio\10.0\Extensions 

This will show if you have a VS2010 installation problem, or whether it is related to the extension (or the interaction of the two extensions).

If it is VS2010, try to repair the installer, if it is an extension, restore and remove half and repeat until highlighted.
