...t, reusable functionality, and lets you delegate some tricky logic to well-tested standard library components. Consider for example:

Why is it important to override GetHashCode when Equals method is overridden?
...ike "return FooId;" is a suitable GetHashCode() implementation. If you are testing multiple properties, it is common to combine them using code like below, to reduce diagonal collisions (i.e. so that new Foo(3,5) has a different hash-code to new Foo(5,3)):

When to use static vs instantiated classes
...
One thing about static methods/classes is that they don't facilitate unit testing (at least in PHP, but probably in other languages too).
