+Summary: Type.GetProperty(string) returns null on ambiguity instead of throwing exception
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+When calling GetProperty("Item") on a Type for a class with an
+overloaded indexer, null is returned instead of throwing
+an AmbiguousMatchException as per .NET 1.1 docs and MS .NET 1.1 behaviour.
+
+Steps to reproduce the problem:
+1. compile test program included
+2. run it
+3. 
+
+Actual Results:
+null returned
+
+Expected Results:
+AmbiguousMatchException thrown
+
+How often does this happen? 
+always
+
+Additional Information:
+A test program PropTest.cs -
+
+using System;
+using System.Reflection;
+
+namespace test
+{
+
+  public class MultiIndexer
+  {
+    public string this[int i]
+    {
+      get { return i.ToString(); }
+    }
+
+    public string this[double d]
+    {
+      get { return d.ToString(); }
+    }
+
+
+  }
+
+
+  public class PropTest
+  {
+
+     public static void Main()
+     {
+       Type type = typeof(MultiIndexer);
+       PropertyInfo pi = type.GetProperty("Item");
+       if (pi==null)
+         Console.WriteLine("got null (not found), should have thrown an
+AmbiguousMatchException");
+       else
+         Console.WriteLine("got pi="+pi);
+
+       // try using them (works fine)
+       MultiIndexer m = new MultiIndexer();
+       Console.WriteLine("int index 1 = "+m[1]);
+       Console.WriteLine("double index 2.2 = "+m[2.2]);
+     }
+  }
+
+}
