MonoDevelop and MonoTouch: what is the runtime version selection about?

I have just upgraded to the MonoDevelop 2.8 Alpha and built my MonoTouch app with it. I noticed that in the build type dropdown, where I can select Simulator debug/release and iPhone debug/release, there are three separate entries:

• Default Runtime
• Mono 2.10.2
• Mono 2.10.1

My MonoTouch version is 4.0.4.1开发者_如何学C. I thought MonoTouch was coming with its own Mono runtime. Does the dropdown make any difference for MT projects?

No, the target runtime doesn't affect MonoTouch. It only matters for "normal" desktop/server .NET projects.
