VS.NET can be used with any source control application that is Microsoft Source Code Control Interface (MSSCCI)-compliant. In this chapter, you’ll learn about using the source code locking and versioning facilities provided by Microsoft’s Visual SourceSafe (VSS) 6.0d, which is the source control application that comes with VSED and VSEA. VSS 6.0d integrates into the VS.NET IDE. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
