Question

Im trying to create a really basic NServicebus.Host application which sends a message every second. I dont want to use any of the NServiceBus persistance stuff which uses RavenDB (ie timeouts/sagas).

Ive done the following:

public class EndpointConfig : IConfigureThisEndpoint, AsA_Server, AsA_Publisher, IWantCustomInitialization
{
    public void Init()
    {
        Configure.With()
            .DisableTimeoutManager();
    }
}

and

public class MessageSender : IWantToRunWhenTheBusStarts
{
    private readonly IBus _bus;

    public MessageSender(IBus bus)
    {
        _bus = bus;
    }

    public void Run()
    {
        Task.Factory.StartNew(() =>
        {
            while (true)
            {
                _bus.Publish(new MyMessage { Timestamp = DateTime.Now });
                Thread.Sleep(1000);
            }
        });
    }
}

however I get an exception on the publish line:

System.Net.WebException was unhandled by user code

This suggests to me that NServiceBus is still trying to connect to RavenDB.

What else do I need to disable to make this example work?

Why is it even trying to connect to RavenDB for a basic publish?

Note: I have no subscribers yet.

Answer 1

It looks like NServiceBus also uses RavenDB for subscription storage by default. By specifying an alternate storage mechanism I was able to get this example working.

            .MsmqTransport()
                .MsmqSubscriptionStorage()
            .DisableTimeoutManager();

and in the app.config

<configuration>
    <configSections>
        <section name="MessageForwardingInCaseOfFaultConfig" type="NServiceBus.Config.MessageForwardingInCaseOfFaultConfig, NServiceBus.Core" />
        <section name="MsmqSubscriptionStorageConfig" type="NServiceBus.Config.MsmqSubscriptionStorageConfig, NServiceBus.Core" />
    </configSections>
    <MessageForwardingInCaseOfFaultConfig ErrorQueue="error" />
    <MsmqSubscriptionStorageConfig Queue="YourQueue" />
</configuration>
