CLR optimization question

Suppose you have a base class with one protected property and one method.

When you instantiate a derived class, obviously there needs to be a copy of
the property specific to that instantiation in memory.

But there *could* be one copy of the method for all the derived objects to
reference. Or does the compiler simply create a class with all the base
class code included and that's what the CLR creates at runtime?

Not really. Each instance has its own copy of any instance fields that
you may use as a backing store for the property, but the property code
is shared by all instances.

Yes, only a single copy of the code is needed.

Thanks for the response.

Yeah, I really was thinking field but said property. Doh!
No.

That's pretty cool.
