If the Solution opened in Visual Studio is under Dimensions Control but does not contain the necessary bindings for Dimensions for Visual Studio, the Attach to Source Control menu option will be available. This scenario is most likely when the Solution has been added to Dimensions CM through one of the other clients as part of a bulk upload or migration activity. This wizard writes the necessary binding information into the solution and project files and delivers these changes so that the solution can be treated as if it was added to source control through Dimensions for Visual Studio.
