+Summary: Explicit cast on null for overloaded method call fails
+
+Description of Problem:
+The runtime fails to use the explicit cast on a null argument 
+
+Steps to reproduce the problem:
+1. create two functions in a class with the prototype: 
+public void F(DataColumn col);
+public void F(DataColumn[] cols); 
+
+2. Call one of the functions with a null value using a cast:
+testClass.F((DataColumn)null);  
+
+3. Step 2 will cause an invalid program exception. It shouldn't.  It 
+should appropriately use the cast to pick the function to call.
+
+Actual Results:
+InvalidProgramException()
+
+Expected Results:
+Correct Method Called
+
+
+How often does this happen? 
+Every time.
+
+Additional Information:
+
+Run test case:  System.Data.ForeignKeyConstraintTest.TestCtorExceptions()
+To reproduce.
