Title
Body
While using dictionary, i always override GetHashCode and Equals ( or provide a custom comparer to the dictionary). What happens behind the covers when i create an anonymous class as key? Sample Code.... var groups=(from item in items group item by new { item.ClientId, item.CustodianId, item.CurrencyId } into g select new { Key=g.Key, Sum=g.Sum(x => x.Cash) }).ToDictionary(item=>item.Key,item=>item.Sum); This code gives me the expected result, but i am not providing GetHashCode and Equals method for the anonymous class. Shouldn't this code fail to group my items on the basis of items in anonymous class??
