Chapter 17. Interoperability
In this chapter we studied mixing managed and unmanaged code running under Windows. We saw how to call legacy COM components from within the managed .NET environment using a Runtime Callable Wrapper, or RCW. We also looked at the use of a COM Callable Wrapper (CCW) to enable a COM client to call a .NET component. Finally, we looked at using Platform Invocation Services (PInvoke), and saw how automatic marshaling is provided for both in and out parameters.
