           Summary: Delegate.CreateDelegate is less strict than MS, but
                    invocation is incorrect
    Classification: Mono
           Product: Mono: Class Libraries
           Version: SVN
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: CORLIB

Description of Problem:

Delegate.CreateDelegate is less strict than MS. Consider the following:

public static void Foo(params object[] args)
{
  Console.WriteLine(args);
}

static void Main(string[] args)
{
  var r = Delegate.CreateDelegate(typeof(Action),
typeof(Program).GetMethod("Foo")) as Action;

  r();
}

On MS, this fails with:

Unhandled Exception: System.ArgumentException: Error binding to target method.
   at System.Delegate.CreateDelegate(Type type, MethodInfo method, Boolean
throwOnBindFailure)
   at ConsoleApplication1.Program.Main(String[] args)

On Mono it success, all good now, but when invoked (as in r()), 'null' is
passed to the method, instead of new object[0].

Actual Results:

'param object[] args' is null

Expected Results:

'param object[] args' is should be 'object[0]'
