+Summary: CollectionBase Indexer's behavior differs from .NET's
+
+Description of Problem:
+
+This method has two bugs:
+BUG#1) Mono Calls OnValidate method before checking if argument is out of
+range. .NET throws ArgumentOutOfRange exception, not calling OnValidate.
+
+BUG#2) After setting the new value into InnerList if OnSetComplete throws
+an exception mono does not undo the transaction.
+
+
+Steps to reproduce BUG#1:
+using System;
+using System.Collections;
+
+namespace PruebaBugCollectionBase
+{
+        class MyCollection: CollectionBase
+        {
+
+
+                protected override void OnValidate(object value)
+                {
+                        throw new ApplicationException("OnValidate Called!!!");
+                }
+
+        }
+
+        class Class1
+        {
+                static void Main(string[] args)
+                {
+                        IList c = new MyCollection();
+                        c[5] = 8888;
+                }
+        }
+}
+
+
+Actual Results:
+OnValidate is called....
+
+Expected Results:
+.NET Framework throws a ArgumentOutOfRangeException not calling OnValidate.
+
+How often does this happen? Always
+
+Steps to reproduce BUG#2:
+namespace PruebaBugCollectionBase
+{
+        class MyCollection: CollectionBase
+        {
+
+
+                protected override void OnSetComplete(int index, object
+oldValue, object newValue)
+                {
+                        throw new ApplicationException("OnSetComplete
+Called!!!");
+                }
+
+        }
+
+        class Class1
+        {
+                static void Main(string[] args)
+                {
+                        IList c = new MyCollection();
+                        c.Add(88);
+                        try {
+                        c[0] = 11;
+                        } finally {
+                        Console.WriteLine("Value c[0]: {0}", c[0]);
+                        }
+                }
+        }
+}
+
+Actual Results:
+Value c[0]: 11
+
+Expected Results:
+.NET Framework returns 
+Value c[0]: 88
+
+How often does this happen? Always
