The project you have chosen cannot be correctly opened from source control.

You are attempting to open a solution or project that was not added to source control using %0. %0 supports opening solutions from source control only when they are added (or bound) using %0.
The user who initially added the solution must use the Change Source Control command to bind the solution to source control in its current location.
