If you want to share your source code that is under source control, you better remove the source bindings before sending your files to avoid the strange Visual Studio warnings when the solution is opened. You can do that by deleting the .vssscc and the .vspscc files and then removing the lines from the project file that start with Scc, but this manual work can be tedious for many projects.
A much simpler solution is to use the VS Unbind Source Control tool from CodePlex that does all that after firing it with a single line of command in command prompt:
VSUnbindSourceControl.exe W:\MyFolder
I learned it. I share it.
