IntroductionThis error can happen when you use Microsoft Team Foundation Server(TFS) and if you don’t have proper binding files. This can happen if the solution is new in TFS and there are no binding files associated with it. You can easily fix this. To fix it, you have to go to
File -> Sourcecontrol-> change source control.
Click on the project which don’t have binding and say bind. This will automatically bind your solution with the source control. Do the same for the entire project which don’t have proper binding.
