OK, the first step of Rikxtensible C# has been done. Ever wanted to print "Hello World" via an attribute? This fragment now compiles, and after running through Rikxtensible C# allows the PrivateImportAttribute to provide the code for TestMethod.

class TestClass
	{
		[PrivateImport(), MethodImpl(MethodImplOptions.ForwardRef)]
		static extern void TestMethod();

		[STAThread]
		static void Main(string[] args)
		{
			TestMethod();
		}
	}

Obviously, this is only a proof of concept at the moment but soon we'll have compile time code injection for C#.
