Compiling UE$ Source Code with Sharpdevelop

Can I Compile the source code using Sharpdevelop instead of Visual Studio?

This is a rather late reply, but the answer appears to be “maybe”.

I was able to compile Lightmass using Engine\Build\BatchFiles\Build.bat -2015 UnrealLightmass Win64 Debug for this other tutorial on getting a swarm setup going. Swarm itself can be compiled with SharpDevelop
