Are classes boxed? .NET

I was wondering, does a class get boxed? I always assumed every class had a virtual table which can be used to identify the class, so does it need to be boxed?

No. Classes are reference types so no need for boxing. Boxing is used to represent values as objects (in order to provide .NET's unified type system). As instances of classes are already objects they never need to be boxed.

No they are not.

Boxing referes to a primite type (int, char, long etc...) being wrapped into a class (i.e. boxed).

Only value types (structs) get boxed. Class instances do not get boxed.
