The project %s appears to have been placed under source control with a different provider configuration than the current one.

It will now be necessary to check out the project file and update it to reflect the current configuration of its source control provider. Be warned however, that if the check out fails and the project is closed without saving, you may be prompted to check it out again the next time you open the project and attempt to save it.
