Our goal is to access this type from .NET. As it stands, this piece of code already compiles into a native DLL. The question that stands before us first is what clients will access this code from now on. In othe

You can think this as the “base class pointer” as every python object are “derived” from PyObject. The code is written using C so the inheritance is really built by hand through inserting a PyObject field into all the subclasses. We’ll see more of t...
