Re: Key compare in Dictionary

I have found this documentation
http://msdn.microsoft.com/en-us/library/xfhwa508.aspx

It vaguely words that a hash is required for the key class.

Perhaps it should be stated more firmly that equal keys *must* have
equal hashes, thus Object.GetHashCode *must* be overridden when
implementing IEquatable or when overriding Object.Equals.

At least the C# compiler warns with "'xxx' overrides
Object.Equals(object o) but does not override Object.GetHashCode()"
...
