When should I use a struct instead of a class?

Question

MSDN says that you should use structs when you need lightweight objects. Are there any other scenarios when a struct is preferable over a class?

As @Simon said, structs provide "value-type" semantics so if you need similar behavior to a built-in data type, use a struct. Since structs are passed by copy you want to make sure they are small in size, about 16 bytes.
