> @colincodefirst First I would suggest to replace Thread.Sleep(500); with await Task.Delay(TimeSpan.FromMilliseconds(500)); Does this change anything? I agree, the rest of the code looks good for me.

> Does dropping support mean, that there is no longer any possibility to use MQTTnet with net48 or netstandard2.0? I would say yes.

> Support for old versions is dropped in version 5 of the library so that the warnings will also disappear. @SeppPenner Do you want to create the PR for version...

Should be done with https://github.com/dotnet/MQTTnet/pull/2016.

@SamProf You can close this, I guess?

Looks good.

You can also take a look at https://github.com/SeppPenner/SparkplugNet which uses ProtoBuf messages over MQTT.

> I think you need to use forward slash to save correctly I think this is correct, yes.

Nice one :) I will provide a new version soon :)
