application (out of process calls).
This component is a singleton object using the shared property manager to
keep data in memory.
What we want to be able to do is passing a function pointer (or an
interfac
I am trying to implement a callback from server to client. But somehow
the code is not getting executed at the client end..

But why are you using a function

Yes, it is possible (and quite easy too...)
Create the delegate callback to be as close to the expected function,
and then put that delegate into the [DllImport] for the unmanaged code.
Then, when you call it

Hello,
I have an API (C style, DLL based) that requires me to register a
callback. The DLL has a function where as one parameter it either gets
a pointer to the function to call or NULL.
Can I somehow pass a delegate in there? Any samples around?
