This is a sample project that demonstrates integration between self-hoted NServiceBus endpoint and an Azure function. In this setup the function plays a role of a handler for PingCommands send from the Sender endpoint.
The function has the following form:
[FunctionName("TheFunction")]
public static void Run([NServiceBusTrigger(QueueName = "main-queue")]PingCommand command, NServiceBusCollector collector, TraceWriter log)
{
log.Info($"NSB function triggered: {command.Text}");
collector.AddReply(new PongReply{Text = $"Hello {command.Text}. Timestamp: {DateTime.UtcNow.Ticks}"});
}It's tiggered via NServiceBusTrigger running on top of ASQ transport that passes the input POCO command. The second arguemnt NServiceBusCollector handles messages generated by the function on execution.
