Use CodeDOM to add functionality to a Library class

Howdy everyone!

I've been hanging out with the Aspect Oriented Programming crowd, and they talk about doing runtime weaving where they add fields and functions to an already existing compiled class in the library using CodeDOM. However, I've been unable to find any source code for how this might be done.

I need code that will take an existing class and add functionality to it at runtime.

If a specific example is necessary, I'd like to take the base class Control and add a virtual function with the signature
 int minXSize();

Anyone have a clue how to do this, or if it's possible? The guys in AOP land say they are doing it, but again, I haven't seen any code.

I know this is a tough question, so I'm throwing out the big points.

Did you investigate VSA, I know it's not quite adding a function at run time however with a little rethought it could help.

For example you could add a public function to the base object that simply ran a script in a known place, thus you'd be kind of giving yourself the flexibility to add what ever you want to the code.

I am also very interested in CodeDOM and like you never got anywhere, I have had a little success with Microsoft.Vsa though.
