PublishAsync doesn't return a result nor exception about mqttnet HOT 4 CLOSED

What exactly means "no result". Is there null returned or is there a wrong reason code?

from mqttnet.

public async Task Foo(byte[] data)
{
await _mqttPublisher.Publish(topic1, data);
await _mqttPublisher.Publish(topic2, data); // continues even though we didn't get a result nor exception
await _mqttPublisher.Publish(topic3, data);
}

How do you expect to get a result if you don't read it into a variable? await _mqttPublisher.Publish(topic2, data); will always proceed unless an exception is thrown and that is alright?

What about something like:

public async Task Foo(byte[] data)
{
    var x = await _mqttPublisher.Publish(topic1, data);
    var y = await _mqttPublisher.Publish(topic2, data); // continues even though we didn't get a result nor exception
    var z = await _mqttPublisher.Publish(topic3, data);
}

from mqttnet.

What I would expect is that this line:

var result = await _mqttClient.PublishAsync(applicationMessageBuilder.Build(), CancellationToken.None);
always have a result stored in that property before returning. And if there is an exception that an exception is thrown. Now we see that it publishes the mqtt command but before the PublishAsync ends we are already executing the next commands

@don-pironet-hatch Please provide a full running example to that we can try to reproduce the problem. The code you posted contains a _mqttPublisher where the implementation is not clear and how it works internally.
