+Actually what I get from MS.NET is InvalidOperationException.
+
+And the expected behavior is different. Here is the modified repro
+(and more importantly, it *compiles*):
+
+--------
+
+using System;
+using System.Collections;
+
+public class Test
+{
+	public static void Main ()
+	{
+{
+    try
+    {
+        // This doesn't work... (Synchronized hashtable, GetEnumerator
+on clone of hashtable)
+        Hashtable hashtable = Hashtable.Synchronized(new Hashtable());
+        hashtable["a"] = 1;
+        IEnumerator enumerator2 = (hashtable.Clone() as 
+ICollection).GetEnumerator();
+        enumerator2.Reset();
+        enumerator2.MoveNext();
+        DictionaryEntry dictionaryEntry2 = (DictionaryEntry)
+enumerator2.Current; // << Throws.
+	Console.WriteLine ("InvalidOperationException is expected.");
+    } catch (InvalidOperationException) {
+	Console.WriteLine ("OK");
+    }
+}
+	}
+}
