Error sending message: No destination could be found for message type

NServiceBus 5.2.10

NHibernate Persistence Enabled

I know this is a basic question, but I have this working in several web endpoints except one new that we are creating from scratch.

I have configured everything in the same way we did before but NSB cant find the destination for message type..

But when run Bus.Send = No destination could be found for message type 

Here is my Bus init code:

BusConfiguration busConfiguration = new BusConfiguration();

busConfiguration.EndpointName(Consts.WebEndpointName);

busConfiguration.PurgeOnStartup(false);

busConfiguration.Transactions().Disable();

busConfiguration.EnableInstallers();

// Start

var startableBus = Bus.Create(busConfiguration);

IBus bus = startableBus.Start();

Logger.InfoFormat("NServiceBus endpoint {0} started successfully", Consts.WebEndpointName);

This is my Web.config entries (MyApp.Namespace1.InternalMessages is the assembly containing internalmessages)

  <!-- NServiceBus-->

  <TransportConfig MaximumConcurrencyLevel="1" MaxRetries="1" />

  <Logging Threshold="DEBUG" />

  <UnicastBusConfig>

    <MessageEndpointMappings>

      <add Assembly="MyApp.Namespace1.InternalMessages"

           Endpoint="MyApp.BackendProcessing" />

    </MessageEndpointMappings>

  </UnicastBusConfig>

  <!-- End Of NServiceBus-->

I have separated classes for configuration in a different assembly (referenced by web project):

This is the message conventions:

public class ConfigMessageConventions : INeedInitialization

    {

        public void Customize(BusConfiguration configuration)

        {

            ConventionsBuilder conventions = configuration.Conventions();

            conventions.DefiningCommandsAs(t => t.Namespace != null && t.Namespace.StartsWith("MyApp.Namespace1") && t.Namespace.EndsWith("Commands"));

            conventions.DefiningEventsAs(t => t.Namespace != null && t.Namespace.StartsWith("MyApp.Namespace1") && t.Namespace.EndsWith("Contracts"));

            conventions.DefiningCommandsAs(t => t.Namespace != null && t.Namespace.StartsWith("MyApp.Namespace1") && t.Namespace.EndsWith("RequestResponse"));

            //conventions.DefiningEncryptedPropertiesAs(p => p.Name.StartsWith("Encrypted"));

            //conventions.DefiningDataBusPropertiesAs(p => p.Name.EndsWith("DataBus"));

            //conventions.DefiningExpressMessagesAs(t => t.Name.EndsWith("Express"));

            //conventions.DefiningTimeToBeReceivedAs(t => t.Name.EndsWith("Expires") ? TimeSpan.FromSeconds(30) : TimeSpan.MaxValue);

        }

    }

Command being sent:

namespace MyApp.Namespace1.InternalMessages.Commands

{

    public class PublishMyEntityCreated

    {

        [Required]

        public int? MyEntityId { get; set; }

    }

}

Thanks a lot

Never mind, right after sending the email I started a step-by-step investigation and found that :

conventions.DefiningCommandsAs(t => t.Namespace != null && t.Namespace.StartsWith("MyApp.Namespace1") && t.Namespace.EndsWith("Commands"));

conventions.DefiningEventsAs(t => t.Namespace != null && t.Namespace.StartsWith("MyApp.Namespace1") && t.Namespace.EndsWith("Contracts"));

conventions.DefiningCommandsAs(t => t.Namespace != null && t.Namespace.StartsWith("MyApp.Namespace1") && t.Namespace.EndsWith("RequestResponse"));

*** The last line should be DefiningMessagesAs instead of (duplicated) DefiningCommandsAs -- The last line was overrriding the first one :)

Sorry for the basic question
