I have been given the full source code to work on locally (C#.NET/XAML/Visual Studio 2010), but I do not have access to TFS.
Every time I open the solution, it always asks for TFS which I have to cancel every time, but the code is now developed locally from here on out and I will not have access.
How do I effectively "disconnect" TFS from this build?
You can either choose to work offline, or unbind the projects:
File->Source Control->Change Source Control
