How to use code from native dll non-statically in vb.net?

Question

My question is more on the concept and less on the actual code.

I have an app in vb.net. I want to port a few classes to native c++ code (not cli) for various reasons. What I want to do is to be able to instantiate and use these classes, like i do in the fully managed app.

I understand that I can call static functions from a native dll, but this is not the case here. I need to instantiate classes and use them through the lifetime of the app.

So the question is, is this possible? And if so, could you point me to the right direction to start?
