I presented a session this morning at TechEd on building applications that work with Windows Vista Sync Center. Sync Center exposes COM interfaces and requires your application to expose COM interfaces.
This is easy, this is Windows software development like it has been for at least 10 years. It is well defined, well known and well supported.
Hearing developers complain about having to use C++ and do COM development today made me realise that the .NET developer generation is missing out on so many areas of the Windows development opportunities.
My advice, go and learn C++ and COM, it is how many of the Windows Vista features are exposed to developers and with good reason.
If you are not prepared to learn how to program your computer then you should question why you are in the software development business.
