Nice! That's a good start.

Those templates are not needed in CSharpBinding, they were moved to
MonoDevelop.IDE since they are not c#-specific.

I think it would be better to add a property somewhere (maybe in
PropertyService) which returns the entry assembly location, and use that
property in all other services, instead of adding the null check
everywhere.

I think it is ok for now.

In the test setup, you shouldn't need to start the IDE. If you need a
parser database just create one using the ParserService:

IParserDatabase pdb = Services.ParserService.CreateParserDatabase ();
