Huh, I have never heard about the royalty free licence or opensourcing of parts of clr. Do you have source for that? Like, the .net core was opensourced just last year, and even the .net micro for resource constrained devices was opensourced in 2010, 2 years after first android device existed. I am not sure how usefull would using mono have been in this case. On the other hand, I would agree that C# 3.0 with its support for lambdas, LINQ, ability to just use 'var' for local variable declaration, e.t.c looks like a much nicer language that what Java 6 SE was.
