Double clicking a C# script will open MonoDevelop instead of Visual Studio



Repro steps:
1. Set Visual Studio as your external code editor in Preferences and double click on a C# script.
2. A popup box saying "Starting Visual Studio" shows up, but then it disappears and MonoDevelop opens instead.

    Still happens most of the time. Probably even more annoying is that it doesn't have every time!

    Please address this... a workaround would be fine, but having a $10,000 licence for a software you can't use is QUITE hurtful.

    It pretty much ignores any option in the drop-down. Changing the .sln and .csproj to the expected tools and versions for 2013 doesn't work either.

    Ridiculous that this is still happening. It's been 3 years (at least) now and they can't get a .cs file to open in the specified editor...

    Problem is still there in 4.3.3. I'm forced to downgrade to 4.2 again, total waste of time.
