The one-stop guide to how COM and COM+ fit into the .NET world

Microsoft® .NET is here, but COM and COM+ will be a valuable part of every Microsoft Windows® programmer's toolbox for years. This in-depth programming guide explains how and where COM and COM+ fit into the new .NET world, demonstrates the new technologies that are available in .NET, and shows how to interoperate between COM/COM+ and .NET. It explains how to use Microsoft Visual Studio® .NET to write traditional COM objects, how to use COM objects in .NET code, and how to use .NET objects as COM objects. It also discusses COM+ topics such as disconnected applications and subscriptions. The authors show you both theoretical and practical approaches-explaining how the mechanisms work and also providing practical advice with sample code to show how to handle interoperability.
