Is it necessary to override == and != operators when overriding the Equals method? (.NET)

Question

Or it\'s advisable to do that? Why?

Answer 1

See Guidelines for Implementing Equals and the Equality Operator (==)

For Value Types (structs) "Implement == any time you override the Equals method"

For Reference Types (classes), "Most reference types, even those that implement the Equals method, should not override ==." The exception is for immutable classes and those with value-like semantics.
