+Summary: [PATCH] MethodInfo.MakeGenericType() returns null when the count of args is unexpected
+
+When users pass a wrong number of Type arguments to
+MethodInfo.MakeGenericMethod(), it should raise ArgumentException, while we
+just return null.
+
+using System;
+using System.Reflection;
+
+class Goo
+{
+        public void Foo<T> () {}
+
+        public static void Main ()
+        {
+                MethodInfo mi = typeof (Goo).GetMethod ("Foo");
+                MethodInfo gmi = mi.MakeGenericMethod ();
+                Console.WriteLine (gmi == null);
+        }
+}
+
+
+Actual Results:
+
+prints "True".
+
+Expected Results:
+
+something like:  Unhandled Exception: System.ArgumentException: The type or
+method has 1 generic parameter(s) but 0 generic argument(s) were provided.
+
+How often does this happen? 
+
+consitently.
+
+Additional Information:
+
+Attaching a runtime patch.
