Yes, the DarkGDK v2.0 is done by a different person and is a major update that will incorporate multiple host languages. So to say you pay once and will get access to C++, PureBasic, Java, VB.NET & C# plus many many more. I don't think .NET is supported as of now but the author has expressed his willingness to support this platform as DGDK v2 is extremely portable and can be translated to any language that supports DLL calls.
