I've got an old project and solution which I've figured out how to build in VS 2015 while using our old TFS version control. Since then we've moved all of our projects to Git. These setup projects require that the project be checked out (which I think is some sort of TFS legacy) if you want to make changes to the metadata (and other things?).
Is there a way to disable this or to fool VS to think that the project is checked out? I need to change the version and the GUID no this project.
