I tried it once a year ago, message was delayed. Immediately switched to another App (QKSMS).

I think you misunderstood my post. I am quite proficient with C#. I just think other languages do it better.

AOT is not where it should be yet, because not all libraries have full stripping support.

Nah, C# suffers from a lot of the same shit Java does. Needing everything to be a class is just no longer a good design choice (if it ever was). AOT support is still lacking. I don’t get, why it does not have typdefs. I think the solution / project structure is unnecessary and I could probably think of more stuff I dislike about C#. But imho, it still beats Java.

Golang is my choice over C# any time. I strongly prefer how interfaces are handled and I actually like the error handling.

Maybe you should add OTLP support? I don’t know how you are ingesting from Fluentbit at the moment, but I think with OTLP basically any log source can be integrated either through the fluentbit OTLP plugin or an OTEL collector.
