"COM and .NET Interoperability" provides a complete overview on the process of building .NET applications that interact (interoperate) with existing COM code. Before digging into that critical topic, author Andrew Troelson offers a concise overview of the COM architecture and provides examples using various COM frameworks (C++, ATL, and VB 6.0) as well as the core .NET managed languages (C# and VB .NET). After covering the preliminaries, the book explores numerous issues that arise in interoperability, including interacting with the Win32 API, dynamically generating source code via System.CodeDOM, creating serviced (COM+) components using managed code, manually editing (and recompiling) .NET metadata, and the process of constructing custom COM/.NET conversion utilities. Both intermediate and advanced developers will welcome the practical information they need to quickly work with COM and COM+ in .NET applications, and learn how to create .NET components that are COM compatible.
