By Andrew Troelsen (auth.)

COM and .NET Interoperability offers a whole evaluate of the method of creating .NET purposes that have interaction (interoperate) with latest COM code. prior to digging into that serious subject, writer Andrew Troelsen bargains a concise review of the COM structure and gives examples utilizing a variety of COM frameworks (C++, ATL, and VB 6.0) in addition to the center .NET controlled languages (C# and VB .NET).

After protecting the preliminaries, the ebook explores a number of concerns that come up in interoperability, together with interacting with the Win32 API, dynamically producing resource code through System.CodeDOM, developing serviced (COM+) parts utilizing controlled code, manually modifying (and recompiling) .NET metadata, and the method of making customized COM/.NET conversion utilities. either intermediate and complex builders will welcome the sensible info they should speedy paintings with COM and COM+ in .NET purposes, and create .NET parts which are COM appropriate.
