Answer 3

Basically, unit test like crazy! I support both mono and C# on a pet project (protobuf-net), and getting it to even compile on the range of different platforms was fun (I support mono, CF, Silverlight, etc). There are a number of compiler bugs in mono (even in the current release), in particular relating to generics - which mean you might need to use slightly different code to get it to compile in all flavors.

Then you need to think about which framework features you need. Avoid anything like WPF/WCF/WF, for example. But if you stick to core 2.0 features you are generally OK. There are still a lot of places where mono throws NotImplementedException, though. In one recent case, there were two ways of doing something: the "old" way worked on mono but was [Obsolete] in MS; the "new" version worked on MS, but was NotImplementedException on mono. Fun!
