How to manually uninstall a Visual Studio 2010 extension?

Question

So I got prompted to download the latest NuGet Package Manager in VS2010. All previous updates (including this) has failed with:
VSIXInstaller.SignatureMismatchExc

Answer 1

If you want to delete/uninstall Nuget package which is applied to multiple projects in your solutions then go to:

1. Tools-> Nuget Package Manager -> Manage Nuget Packages for Solution

2. In the left column where is 'Installed packages' select 'All', so you'll see a list of installed packages and Manage button across them.

3. Select Manage button and you'll get a pop out, deselect the checkbox across project name and Ok it

The rest of the work Package Manager will do it for you.
