// 1. User renames a file in the above project sytem relying on MPF
// 2. Our rename funstionality implemented in this method removes and readds the file and as a post step copies all msbuild entries from the removed file to the added file.
// 3. The project system mentioned will trigger an msbuild re-evaluate with the new item, because it was listening to OnItemAdded.
// The problem is that the item at the "add" time is only partly added to the project, since the msbuild part has not yet been copied over as mentioned in part 2 of the last step of the rename process.
// The result is that the project re-evaluates itself wrongly.
