After trying to compile a project in P12, I get a "monodroid : error 1:
Mono.Linker.ResolutionException: Can not resolve reference: System.Func`2" that
didn't happen in P11.2.

I could track down the problem to the line where it causes the error, it's a
LINQ expression:

                var usuarios = from Obj_Usuario usuario in BancoSqo.Banco
                               where usuario.User_Codigo ==
Convert.ToInt32(Codigo)
                               select usuario;

Output:

Also, I tried this:

                int codigo = Convert.ToInt32(Codigo);
                var usuarios = from Obj_Usuario usuario in BancoSqo.Banco
                               where usuario.User_Codigo == codigo
                               select usuario;

It doesn't work either. Then I tested with the actual number:

                var usuarios = from Obj_Usuario usuario in BancoSqo.Banco
                               where usuario.User_Codigo == 1
                               select usuario;

The error is the same. I had to reinstall P11.2 and now it works fine again.

Reproducible: Always

Steps to Reproduce:
1. Just use any LINQ expression like I mentioned and the compilation fails.
2.
3.
