Hi,
the behavior of generic SortedList between .Net and Mono are different.
In depth when you use enumerator from Keys and Values you are able to remove an
element from the sorted list and go on in the enumerator without have any
exception. Moreover you not able to reset the enumerator where is possible on
Net.
THis behavior is tested on VS C# Express
Changes on UnitTest are also provided.
Reproducible: Always
Steps to Reproduce:
// This code show the bug
// The only exception that need to be generated is capture.
// If you run this application without fix you got a uncaptured exception
//
using System;
using System.Collections.Generic;
