MonoDevelop Not Recognizing .NET 4.5 Support

Question

I have recently installed both Mono (3.0.8) and MonoDevelop (4.0) on my linux machine (Arch linux). I have a Solution that contains a number of projects that depend on the .NET 4.5 Framework. (Specifically, I'm working with the Casanova project) However, MonoDevelop does not seem to recognize the .NET 4.5 framework for projects; it only recognizes .NET 4.0 and prior as a target framework.

I know Mono 3.0.8 supports basic .NET 4.5, but I'm not sure why MonoDevelop cannot see this. When I create a project as Mono / .NET 4.0 and attempt to build it, it fails to find definitions for .NET 4.5 specific fields and members. Is there a way I can force MonoDevelop to read in .NET 4.5 projects?

Solution

I have built Mono and MonoDevelop from Github sources and it seems to have some .NET 4.5 support:

Not sure what about F#, I wasn't able to install F# addon yet.

The Mono version from Github master branch is Mono 3.0.4 (master/b23a610 Thu Mar 7 20:47:00 MSK 2013) for me, not 3.0.8.
