Thank you for applying/enhacing the patches. I'll check it out.

This code will work on both of Mono and MS.NET, but will fail without 
the WriteGenericSignature patch:

AssemblyBuilder ab = AppDomain.CurrentDomain.DefineDynamicAssembly(new 
AssemblyName("myassembly"), AssemblyBuilderAccess.Save);
ModuleBuilder mb = ab.DefineDynamicModule("myassembly", "myassembly.dll");
TypeBuilder tb = mb.DefineType("mytype", TypeAttributes.Public);
tb.DefineGenericParameters(new string[] { "T", "U" });
ConstructorBuilder cb = 
MethodBuilder method = tb.DefineMethod("mymethod", 
MethodAttributes.Static | MethodAttributes.Public, tb, Type.EmptyTypes);
ILGenerator ig = method.GetILGenerator();
ig.Emit(OpCodes.Newobj, cb);

Although using a generic type definition directly makes little sense, 
neither makes using tb.MakeGenericType(tb.GetGenericArguments()) much 
more sense, since you still can use the latter in a context that has 
fewer generic arguments.

I also removed support for the TypeForwardedToAttribute and DefaultParameterValueAttribute pseudo custom attributes (because I realized that supporting them is incompatible with my goal to be a drop in replacement for System.Reflection.Emit).
