Let me explain my situation. I had an ASP.NET project
packages
EntityFramework6.1.1
.
.
MyProject
App_Data
.
.
MyProject.sln
under source control in GitHub. I copied those project files onto another machine. Now I want to put that project on the other machine under source control in TFS. The problem is that somehow Visual Studio knows/thinks the project is under source control in GitHub and so it doesn't let me add it to TFS (the option for TFS that is there when you right-click the solution is not there). Yet, I've looked through the source files and can't find any references to GitHub. Where would they be? I want to get rid of them.
