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.
