I've been test driving Microsoft's awesome new Visual Studio Tools for Git for since it was announced on January 30 and decided to take the plunge and make it the default source control provider when creating a new project. The problem is that my aim was apparently off and I left "Team Foundation Version Control" selected when I checked "Use the selected system when creating new projects in the future" and clicked OK. No problem, right? I started digging through Visual Studio's settings pages but came up blank when trying to find the obscure checkbox that will allow me to reset my inadvertent series of misclicks. AppData folders? Wrong again. Finally after slogging my way through the registry, I finally found the correct setting to change stored in the key ChooseSourceControlDefaultSccProvider located in \\HKCU\Software\Microsoft\VisualStudio\11.0\TeamFoundation\SourceControl\General. Setting this key back to "0" (it was set to "1") restores the dialog that allows you to select your source control provider when creating a new project. Piece of cake, right?
Did this help you? Is there an easier way to reset this? Let me know in the comments!
P.S. If you're a Git or TFS user and haven't tried the Visual Studio Tools for Git, why not?
