17 | public ExtarnalService(MqttClientServiceProvider provider) 18 | { 19 | mqttClientService = provider.MqttClientService; 20 | } 21 | } 22 | ``` 23 | 24 | 25 | 26 | **Configuration** 27 | 28 | Configure your MQTT settings in `appSettings.json` 29 | 30 | ```json 31 | "BrokerHostSettings": { 32 | "Host": "localhost", 33 | "Port": 1883 34 | }, 35 | 36 | "ClientSettings": { 37 | "Id": "5eb020f043ba8930506acbdd", 38 | "UserName": "rafiul", 39 | "Password": "12345678" 40 | }, 41 | ``` 42 | 43 | 44 | 45 | **Reconnecting** 46 | 47 | Reference Code：https://github.com/dotnet/MQTTnet/blob/master/Samples/Client/Client_Connection_Samples.cs 48 | The implemented code is in `MqttClientService.cs` 49 | 50 | 1.
