title: Git extension does not work in Visual Studio 2017; Is it a known issue?
body: <p>Before trying the official release of Visual Studio 2017, I installed Visual Studio 2017 RC and found that my existing Git Repository is not recognized. Even though I made sure that the Source Control plugin is set to Git as shown in the following picture.</p>

  <p>Then, I thought, maybe it is just because of RC edition.
  Anyway, today official version of Visual Studio 2017 released and I have installed again. I see the same problem. Did anyone face the same issue? What is the solution to this problem? I do not think I need to install Git Extension separately as looks like Visual studio already has that extension preinstalled.</p>
