Is it still necessary to overload the == to cater for its normal operation?

Question

the reason I asked the question was because after reading the msdn advice on overloading this operator at the end of the page it mentioned:

A common error in overloads of operator == is to use (a == b), (a == null), or (b == null) to check for reference equality. This instead results in a call to the overloaded operator ==, causing an infinite loop. Use ReferenceEquals or cast the type to Object, to avoid the loop.

so I was wondering if I should implement the overload for the standard scenario.

Answer 1

No! Do not mess with reference equality unless you know what you are doing. Implement IComparable Equals method if you need to.

Edit: For a better picture look up Effective C#, Item #9.
