The term "difference" is not logically accurate, inapplicable to most cases.

So, something practically most important:

Struct is a value type, class is a reference type.

And one false difference which many people mistakenly think off. Many don't know that struct can also implement interfaces. They can, exactly as classes. But this is very non-trivial, because if a struct object is accessed via a variable/member of interface type, it works like a reference. Besides, this introduces a more advanced kind of polymorphism: the polymorphous set is abstracted not only from the runtime types, but even from the nature (value or reference) of these type. Besides, the same struct/class can implement more then one interface and participate in more then one unrelated polymorphous sets.
