MVC2 is not supported in Visual Studio 2012

The title pretty much says it all, there is no way to open an MVC2 project within Visual Studio 2012, there is no "auto upgrade" path either! If you attempt to convert a solution containing an MVC2 project you will probably see the following error message:

Subtype: '{F85E285D-A4E0-4152-9332-AB1D724D3325}' is unsupported by this installation.

If you do, then the only real solution appears to be graft the existing MVC2 project into an empty MVC3 or MVC4 project and update references accordingly - bit of a chore no matter what approach you choose / prefer.
