To add all of your source file data to Rational® ClearCase® control, you must add project files (for example, .dsp or .vpb) and the source files that belong to the project. You do not need to add Visual C++ workspace or Visual J++ solution files to source control because these files contain information regarding IDE settings for the current session. Visual Studio dialog boxes present the files that it recommends you add to source control.
In Visual Studio .NET, you have no control over what files are added to source control.
