This library was originally developed by Morten Kvistgaard with a lot of contributions from F. Chaxel and Steve Karg and the BACnet Stack (in C). It is used as a core library in YABE (Yet Another BACnet Explorer). It has been forked here from the SourceForge SVN source, splitted into separate repositories and made available to download via NuGet.
You can get it by grabbing the latest NuGet package.
See examples to learn how to use this library.
