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.

im having the opposite problem, the visual studio keeps on opening up rather than mono develop, i think the problem is i didn't install the right version and i cant find any other version so if anyone can post a link to the download sight that would be great.

I'm currently experiencing this issue with 5.6.1f1 and VS 2017 community. Even if the VS is running, double clicking any script launches the mono develop and shows the error: "Could not load project 'project_name.csproj' with unknown item type '{guid}'".

Manually renaming the monodevelop .exe to something else, will load Visual Studio.

YASIN.GHANNAM Definitely has it right. That was exactly my problem, I had changed visual studio to always run as administrator and unity was not. When I ran Unity as administrator, Visual Studio opened up correctly.

From http://forum.unity3d.com/threads/double-clicking-a-c-script-should-open-visual-studio.251358/#post-2431199
Have Visual Studio 2015 sp1. After upgrading from Unity 5.2.3f1 to 5.3.0f4 I began seeing this problem: "....started saying it was opening VS and opened Mono Develop instead...."
I upgraded to 5.3.1f1 and I am still seeing the same problem with an extra symptom:
Now Visual Studio must Migrate the project to the current Visual Studio version. While the version upgrade is in process, Mono Develop opens.
Other observations I see:
The VsHub.exe tree of processes gets started. (Looks normal)
devenv.exe gets started and just silently idles.
The new devenv (2015sp1) includes a child process named PerfWatson2.exe when started manually; the Unity kick off never includes this child process.
A workaround exists:
Manually open Visual Studio and open the Unity project. Now double clicking a file will open it in Visual Studio but the whole project has to be migrated each time... it appears Unity is not accepting the Visual Studio Migration changes.

This might help:
Run Unity as an administrator(right click, then choose Run As Administrator).
I had set Visual Studio to run as administrator by default, while I always ran Unity without any administrator privilege. I guessed this might be the issue, so I ran Unity as administrator, and it worked.

Same things happens in Unity 5.2.3f1, and I have adjusted the preferences to always start C# files with VS...
