I updated to Unity 5.3.1p1 and within that came MonoDevelop 5.9.
Before that, I was using Unity 5.2 and MonoDevelop version 4.something. And before updating, I used Custom Dark theme from an awesome guy named Sebastian League (check out his videos!). It was added by ‘Tools → Options → Text Editor → Syntax Highlighting’ and then pressing ‘Add’ and selecting the right file.
But if I do it now, after ‘Add’ and ‘Open’, nothing happens. It goes back to ‘Syntax Highlighting’ window, but no theme added.

I tested with duplicating other themes and tried different ways of doing it, but nothing.
Any help appreciated, thanks!
I have the same problem .But today I got around it.
My MonoDevelop 5.9.6 with Unity 5.3.
Reason for import but nothing Happened:
Mono is very sensitive and strict for the format of the *.json file(more loose for *.vssettings file in my experience).
E.g .`{ **!!--space or Tab here--!!** "name":"Background(Read Only)", "color":"#D9D5C3" },Maybe have many points that matter ,So you'd better to compare you json with default ones (you can export one for comparing by BeyondCompare or other tool you perfer).
