How can you disable Git integration in Visual Studio 2013 permanently?

As you said you can disable the source control plugin going to:

• Tools / Options
• Check "Show all settings"
• Source Control / Plug-in Selection
• Set "Current source control plug-in" to "None"

Then, as Ade Miller says: Restart Visual Studio.

My Visual Studio was working really slow since the git plugging was enabled and I managed to disable it "persistently across sessions" following this steps.

Hope it helps.

I had the same problem with Visual Studio 2015, where NoGit extension wasn't even allowed to install. I use the "open last solution on start-up" option so I thought that maybe this was somehow connected to the problem.

So I simply closed my solution before going to "Tools - Options - Source Control", then turned it off, restarted VS and - voila, SC stayed turned off! Hope it stays so in other solutions as well.

For me, creating the repository with the following command fix the problem:

git init --separate-git-dir _git

Since it doesn't create a .git directory, only a .git file pointing to the real repository directory, e.g.:

gitdir: C:/tfs/ProjectName/Main/_git

Visual Studio (at least up to VS2015 Update 3, which is what I use) doesn't notice it!

This worked better than the environment variable stuff because Git Extensions (that I'm using) had problem supporting that, but dealt with the .git file pointing to a _git folder perfectly.
