It provides a MQTT client and a MQTT server (broker) and supports v3.1.0, v3.1.1 and v5.0.0 of the MQTT protocol. -* [Core] Fixed wrong versions in nuget packages. -* [Server] The TCP address is now reused when starting which should prevent "port in used" error when restarting. +* [Server] Moved new socket options to TCP options to avoid incompatibility with Linux hosts.
