This is a stack trace (private info removed) running on OSX. The culprit seems to be this assignment, it throws an exception on OSX. https://github.com/ela-compil/BACnet/blob/22537b585d389f662cbb2a900fb55169d3f01d3e/Transport/BacnetIpUdpProtocolTransport.cs#L103 

Unhandled exception. System.Net.Sockets.SocketException (45): Operation not supported
   at BacnetIpUdpProtocolTransport.Open() in BacnetIpUdpProtocolTransport.cs:line 127
   at BacnetIpUdpProtocolTransport.Start() in BacnetIpUdpProtocolTransport.cs:line 207
   at System.IO.BACnet.BacnetClient.Start()

In my patched version I just catch and ignore, but would be nice to know how to actually handle this.
