Fix wrong plugin installation

[Dmitry Dolotovskikh]

Hi

I created second plugin from existing by copy&paste "pattern". Just only package id has been changed.

Next I installed new plugin into different experimental instance. Now there both plugins are installed. But Extension Manager can't be opened because follow exception. How to uninstall any plugin?

Frankly saying there is exception right after VS starts:

To be honest, I don't know. I don't see how that call stack can give a NullReferenceException.

If it's just an experimental instance, I'd be tempted to just reinstall ReSharper - not the subtlest of solutions, but it'll be the easiest. By default it will reinstall any plugins, but in the installer options, you can tell it not to. Uncheck that box and reinstall.
