Actually we use VSS. CheckIn and CheckOut work fine.

But now we need the following: we have a version, that our customers can use. In the meantime we develop new things. But maybe we have to make changes in the customer-version. Such a workflow isn't possible within VSS.

A collegue told me we may use cvs. But I'm not sure, if cvs works with Visual Basic .Net.

Does anyone have any experience??
