Sealed Class : Once a class is defined as sealed class, this class cannot be inherited.
If you have ever noticed, structs are sealed. You cannot derive a class from a struct.
One of the best usage of sealed classes is when you have a class with static members
public sealed class MySingleton {
public static readonly MySingleton Instance = new MySingleton();
private MySingleton(){ }
}
