Description David Fowler 2015-04-06 07:50:02 UTC
class MainClass
{
    public static void Main (string[] args)
    {
        var d = new Dictionary<string,string> ();
        d.Add ("x", "1");
        d.Add ("x", "2");
    }
}

On the MS impl it says "An item with the same key has already been added" 
On mono it says "An element with the same key already exists in the dictionary"
