How to stop unity from losing source control information

Every time I fire up Unity, it re-writes the solution and project files even though there are no changes which Visual Studio detects and asks for a reload. It is VERY annoying. (Devs, could you write those files to a temporary buffer and do a compare before writing that buffer to file? This would prevent constant reloads.)

The main annoyance though is that every time it does that, I lose my source control information and I have to rebind the project. I often have to kill unity to get out of infinite loops and having to rebind the project is getting very frustrating. Devs, could you check the existing solution and add the GlobalSection(TeamFoundationVersionControl) = preSolution [...] EndGlobalSection section to the aforementioned buffer?

In the meantime, does anyone know how I could stop unity from losing the source control information? I tried to create a copy of the .sln and using that instead but it did not work. Unity still overwrites it. Thank you.
