One question: The APIs here appear to be machanically created from some other source - from things like "System.Windows.Forms.NativeMethods"? The functions are present, but not the structures and data types used in the params. Any plans to do a mechanical dump of the structures as well? The real magic of marshalling is getting the param types set up correctly, which for structures can be quite a pain.

.

I would love to have a downloadable solution that has all of the signatures, structures, consts, etc., like Microsoft's SafeNativeMethods and UnsafeNativeMethods. -- Omer van Kloeten
