How to view 4.0+ documentation

[FeiSuperMe]

The Client tab in this wiki page has the following description:
These samples are only valid for version 3. Please check the Samples directory for samples and documentation for version 4.0+.

Where can I get this 4.0+ documentation from?

There is no wiki / documentation for that but examples are under https://github.com/dotnet/MQTTnet/tree/master/Samples.

Ok.Thank you for your reply.

I'm trying to use MQTTnet.4.3.7.1207\lib\net461. But the MqttClientFactory from samples doesn't exist in this .dll
