The binding information for project %1 could not be retrieved from its source control provider. This project may have been placed under source control with a different provider configuration from the current one.

To keep source control working for this project, %0 will now check out the project file so that the binding information can be saved in it. However if the check out fails and the project is closed without saving, the next time it is opened, it will appear to no longer be under source control.
