MQTTnet 3.0.12

MQTTnet is a high performance .NET library for MQTT based communication. 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.

No packages depend on MQTTnet.

* [LowLevelClient] Fixed a null reference exception when connecting to a not existing server (thanks to @SGStino). * [RcpClient] Adjusted some namespaces (BREAKING CHANGE!). * [AspNetCore] Adjusted some namespaces (BREAKING CHANGE!). * [Server] Adjusted some namespaces (BREAKING CHANGE!). * [Server] Added state checks (throw if not started etc.) for most server APIs. * [Server] Exposed real X509Certificate2 (instead byte array) to TLS options (thanks to @borigas). * [Server] Fixed memory leak with TCP sockets (MqttServer is now Disposable!) (BREAKING CHANGE!). * [Core] Fixed a null reference exception in the MqttTcpChannel with WriteAsync and ReadAsync. * [Core] Added server interceptor for undelivered messages (thanks to @cshark-inator). * [nuget] Added support for SourceLink (thanks to @JTOne123).
