VS2012: Property Pages isn't opening: Object reference not set to an instance of an object

Question

I\'m on Visual Studio Premium 2012, Version 11.0.50727.1 RTMREL, Windows 7 Enterprise (SP1).

When I right click on the Solution, and click Properties, I get a popup

Answer 1

This is my experience with the problem: (Running VS2012 as administrator, hoping that some setting would be sorted out).

I have a solution with two MVC projects and other projects. If I unload the two MVC projects without restarting VS, the problem is still there. After restarting VS, with the two projects not loading, but showing in Solution explorer, the problem disappears. Load the two projects back, Solution properties still work, but after a restart the cycle restarts.

NOTE: There is no difference in the projects and solution files when the two MVC projects are not loaded.
