代码拉取完成,页面将自动刷新
同步操作将从 shamork/MQTTnet 强制同步,此操作会覆盖自 Fork 仓库以来所做的任何修改,且无法恢复!!!
确定后同步将在后台操作,完成时将刷新页面,请耐心等待。
MQTTnet is a .NET library for MQTT based communication. It provides a MQTT client and a MQTT server. The implementation is based on the documentation from http://mqtt.org/.
This library is available as a nuget package: https://www.nuget.org/packages/MQTTnet/
