Source Code: bladewolf55/posh-git-tfvc: A PowerShell environment for Git, modified to use with TFVC-based solutions

I created this version of posh-git to handle a specific use case: a developer works for a company that requires using TFVC, but she wants to use Git locally to gain its rapid branching/merging abilities. Yet, she also wants to get the benefits of using Visual Studio's TFVC integration, namely CodeLens information.

Visual Studio supports both TFVC and Git version controls, and you're allowed to choose which one to use via Options > Source Control. Except, not really. If your solution has a .git folder or .git file, VS assumes you're using Git even if you also have a $tf file or your solution/projecs are configured for TFVC.

The general solution is:

• Rename .git to _git
• Set environment variable GIT_DIR to the full path to the _git folder
• Set environment variable GIT_WORK_TREE to the full path to the working folder
• Add line to .gitignore to ignore the _git folder

My modifications to the GitUtils.ps1 file accomplish that.

As a bonus, in the test _git folder there's a file containing a Git alias to initialize a repo using a _git folder and the appropriate .gitignore and .tfignore changes.

It's not fancy, and I'm sure a better developer can improve on it.
