Azure Service Bus Send/Reply Sample

NuGet Package: NServiceBus.Transport.AzureServiceBus (2.x)
Target Version: NServiceBus 7.x


An environment variable named AzureServiceBus_ConnectionString with the connection string for the Azure Service Bus namespace.

Code walk-through

This sample shows a basic two-endpoint scenario exchanging messages with each other so that:

  • Endpoint1 sends a Message1 message to Endpoint2.
  • Endpoint2 replies to Endpoint1 with a Message2 instance.

Transport configuration

var endpointConfiguration = new EndpointConfiguration("Samples.ASBS.SendReply.Endpoint1");

var transport = endpointConfiguration.UseTransport<AzureServiceBusTransport>();

var connectionString = Environment.GetEnvironmentVariable("AzureServiceBus_ConnectionString");
if (string.IsNullOrWhiteSpace(connectionString))
    throw new Exception("Could not read the 'AzureServiceBus_ConnectionString' environment variable. Check the sample prerequisites.");

Viewing messages in-flight

The following queues for the two endpoints can be seen in the Azure Portal or a third-party tool:

  • samples.asbs.sendreply.endpoint1
  • samples.asbs.sendreply.endpoint2
  • error
