Yep, kBessa is correct. Apex is the creator of the DGDK.NET package but it is a wrapper for the original DGK. That means that his wrapper exposes the functions in the original version to .NET languages via COM Interop. This also means that the DGDK.NET is wholly dependant on the underlying version. If TGC adds or changes anything Apex has to adjust his wrapper to stay in line with it. The same premise holds true for the help files. Apex uses the help files from the original kit and applys a process to convert the help to the .net equivalents. He is not responsible to fill in missing or unclear documentation, this was tgc's responsibility from the get-go.
hope that clears it up a little.
