What doesn't get inherited in .Net?

I guess I was surprised to learn that Implements or <Serializable()> do not get inherited fr开发者_开发技巧om class to class which means that it must be redefined each I want to recreated those behaviors. I was wondering what else isn't inhertible in .Net? Thanks

These are 2 different items: interface and attribute inheritance.

The Inherits portion refers to how interfaces behave across class hierarchies. Interfaces are indeed inherited. If a given base class implements IFactory then all of it's derived types will. There are certain language oddities on how a derived class can re-implement the interface or specific methods. However at a .Net level once a base class implements an interface all derived classes will as well.

Whether or not an attribute is inherited depends on the value of AttributeUsage.Inherited on the AttributeUsage for the given attribute. In the case of Serializable it's marked as Inherits=false and won't be inherited. Every attribute must pick their own behavior here.

The long answer would take too long, but the short answer is any class using the sealed (c#) or NotInheritable (VB.NET) modifier.
