Visual Studio editor not showing any text [duplicate]

Question

I have been using VS for many years. Today I have encountered a very strange problem with visual studio 2013. Suddenly for some reason I am unable to see any text in the editor window. I've tried reloading the files, redocking each window, restarting VS, restarting my machine and resetting all my settings in Tools -> Import and Export Settings. At present I'm completely stuck as I can't do anything. The tab for each opened file appears at the top as expected but just a blue pane. I'm hoping this is something daft!

Answer 1

I just had the same Problem. However MVVM Light is not installed. I deactivated all extensions that to my knowledge could interfere with the editor and restarted. Problem solved. Then I reactivated the extensions bit by bit, now all are active again and the problem is still gone.

Answer 2

This was caused by the installation of MVVM Light via the extension manager. I uninstalled it and it went away. Installing the required dlls via nuget didn't have the same issue.
