Using centralized routing configuration

The sample demonstrates how to use a file to describe the logical routing topology.

Prerequisites

Make sure MSMQ is set up as described in the MSMQ Transport - NServiceBus Configuration section.

Running the project

1. Start the solution.
2. The text Press <enter> to send a message should be displayed in the Client's console window.
3. Hit enter several times to send some messages.

Verifying that the sample works correctly

1. The Sales console display information about accepted orders in round-robin fashion.
2. The Shipping endpoint displays information that orders were shipped.
3. The Billing endpoint displays information that orders were billed.

Code walk-through

This sample contains four projects. All these project make use of a shared routing file.

<endpoints>
  <endpoint name="Samples.FileBasedRouting.Sales">
    <handles>
      <command type="PlaceOrder, Shared"/>
    </handles>
  </endpoint>
  <endpoint name="Samples.FileBasedRouting.Billing">
    <handles>
      <event type="OrderAccepted, Shared"/>
    </handles>
  </endpoint>
  <endpoint name="Samples.FileBasedRouting.Shipping">
    <handles>
      <events assembly="Shared"/>
    </handles>
  </endpoint>
</endpoints>

For the purpose of the sample, the file is stored in the local file system. The routing mechanism based on the contents of the file is enabled by following code:

var transport = endpointConfiguration.UseTransport<MsmqTransport>();
var routing = transport.Routing();
routing.UseFileBasedRouting(@"..\..\..\..\endpoints.xml");
