Casting generic type “as T” whilst enforcing the type of T

Question

I\'m missing a trick here I think and can\'t believe I\'ve never done this before. However, how can I cast a generic type using the as keyword?

[Serializable]

Read up on Constraints on Type Parameters in C#.

In this particular case, you must ensure that T is a class:

public abstract class SessionManager
    where T : class, ISessionManager
