+Summary: System.Int32 is not a Subclass of according to Type.IsSubclassOf()
+
+Description of Problem:
+
+System.Int32 is actually a subclass of System.ValueType but this is not
+reflected in the return value from Type.IsSubclassOf when passed the two types.
+
+The MS .NET runtime correctly returns true in this case
+
+Steps to reproduce the problem:
+
+The following code:
+
+using System;
+
+class T {
+  
+  public static int Main ()
+  {
+     Type t = Type.GetType ("System.Int32");
+     Type f = Type.GetType ("System.ValueType");
+
+     if (t.IsSubclassOf (f))
+        return 0;
+     else
+        return 1;
+  }
+
+
+Actual Results:
+
+return value : 1
+
+Expected Results:
+
+return value : 0
+
+How often does this happen? 
+
+Everytime.
+
+Additional information:
+
+This bug needs to be resolved before bug #45127 can be fixed with my patch
