Questions & Answers

The version of mono (The library not the editor) for the scripting runtime version:

  • Stable (.Net 3.5 equivalent)
  • Experimental (.Net 4.6 equivalent)

After digging through the reference. The stable one use unity subset of .Net 3.5 while the experimental use actual .Net 4.6

Is the Unity .Net 3.5 subset are still mono or result of collaboration between Unity and Microsoft?

@RalphWeis You can check what version of MonoDevelop you have installed by first opening up MonoDevelop (open any script in your project -or- browse to your Unity install folder>MonoDevelop>MonoDevelop shortcut).

Once MonoDevelop is opened go to Help>About, the current installed version should show up there.
