Expert .NET and COM Interoperability
Duration:  4 Days
Description
In terms of software longevity, Microsoft's COM architecture has enjoyed a long and happy life. With the advent of the .NET Platform, programmers are now faced with the task of learning an entirely new way of building, deploying and viewing software. Once a developer understands that .NET has nothing to do with COM whatsoever, the next task is learning how to allow these two distinct frameworks to co-exist in harmony (after all, you really don't want to recode all your COM binaries do you?). Intertech Inc's Complete COM / .NET Interoperability course will enable the seasoned software developer to build .NET applications making use of legacy COM(+) types as well as COM applications making use of .NET types. This class views the interoperability process from a low level and digs deep into the role of PInvoke, the RCW and CCW.
