Error: Below error occurs when adding the project to source control.
The item C:\VS2017Projects\<projectName>.rnrproj has been cloaked.
The item C:\VS2017Projects\<ProjectName>.rnrproj has been cloaked.
Solution:
Check the source control workspace mapping, there could be some additional mapping to this project, you need to delete this additional mapping (honestly, I couldn't figure out how this was added) and try to add your project to the source control again.
