System topics ?

[RCdotNet]

Hi,
I'm new here and I have a little question about MQTTnet. Is there any System topics implemented?
I was not able to find any reference to that.
Thanks in advance!

System topics are not yet supported neither is the support planned yet. Check out #1258:

No it is currently not supported and not planned yet. But you can build this on your own via sending a reply on certain topics.
