+Summary: calling overloaded methods with varargs fails
+
+Description of Problem:
+when attempting to call overloaded methods that use variable argument lists
+  the compiler reports an Ambiguous call error (  CS0121 ).
+the following code sample demonstrates this behaviour:
+
+using System;
+
+public class Harness {
+    public static void Main( string[] args ) {       
+       MonoTest2 test = new MonoTest2();
+       test.method1("some message" , "some string");
+    }
+}
+
+public class MonoTest
+{   
+    public virtual void method1( string message, params object[] args) {
+       
+    }
+    public void testmethod(){              
+        method1(  "some message" , "some string");
+    }
+ }
+       
+public class MonoTest2 : MonoTest {
+
+      public override void method1(string message, params object[] args) {
+      }
+      public void testmethod2(){
+        method1( "some message " , "some string");
+      }
+}
+all calls to the overridden method1 on MonoTest2 cause the following
+compiler errors:
+MonoTest.cs(6) error CS0121: Ambiguous call when selecting function due to
+implicit casts
+MonoTest.cs(6) error CS-0006: Could not find any applicable function for
+this argument list
+
+The sample code compiles cleanly using csc.exe.
