Programaticly Configuring NServiceBus

I just started implementing a PubSub system for our company using NServiceBus. Overall if has been super easy to setup. The samples are a great starting point and everything is pretty self explanatory.


However as I was trying to roll it out into production I realized that using the standard Spring configuration wasn't going to work for us. I wanted the name of the Msmq input queue to be specified programatilcy instead of via a config file. I knew it had to be possible but I had a really tough time figuring out how to do it. All the samples I could find were about how to set things up with Spring. So I though I would share how I did it.


The standard example shows:

NServiceBus.Configure.With()

    .XmlSerializer()

    .MsmqTransport()

        .IsTransactional(false)

        .PurgeOnStartup(false)

    .UnicastBus()

        .ImpersonateSender(false)

        .LoadMessageHandlers()

    .CreateBus()

    .Start();

So to dynamically set the MsmqTransoprt values you can write the following:

Configure configure = NServiceBus.Configure.With().SpringBuilder();

MsmqTransport transport = configure.Configurer.ConfigureComponent<MsmqTransport>(ComponentCallModelEnum.Singleton);

transport.InputQueue = "DynamicQueueName";

transport.NumberOfWorkerThreads = 1;

transport.ErrorQueue = "DynamicErrorQueue";

transport.MaxRetries = 5;

configure

    .XmlSerializer()

    .UnicastBus()

        .ImpersonateSender(false)

        .LoadMessageHandlers()

    .CreateBus()

    .Start();

This works for me, I have no idea if that is the best practice or if there is a better way to set these values programaticly. Hopefully this helps you and saves you from some the headache I went through (it always seems pretty simple once you get it figured out). Please let me know if you know a better way to do this.
