My GenericHost hosted service is failing to start with the following message:

My endpoint configuration looks like:
public class ServiceEndpointConfiguration
: IConfigureThisEndpoint, AsA_Publisher, IWantCustomInitialization
{
public void Init()
{
// build out persistence infrastructure
var sessionFactory = Bootstrapper.InitializePersistence();
// configure NServiceBus infrastructure
var container = Bootstrapper.BuildDependencies(sessionFactory);
// set up logging
log4net.Config.XmlConfigurator.Configure();
Configure.With()
.Log4Net()
.UnityBuilder(container)
.XmlSerializer();
}
}
And my app.config looks like:
<configSections>
<section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig, NServiceBus.Core" />
<section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig, NServiceBus.Core" />
<section name="Logging" type="NServiceBus.Config.Logging, NServiceBus.Core" />
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false" />
</configSections>
<Logging Threshold="DEBUG" />
<MsmqTransportConfig

ErrorQueue="NServiceBus.Errors"

<UnicastBusConfig

</MessageEndpointMappings>
</UnicastBusConfig>
<connectionStrings>
<add name="Db" connectionString="Data Source=..." providerName="System.Data.SqlClient" />
</connectionStrings>
<log4net debug="true">

</root>
<logger name="NHibernate">

</logger>
</log4net>
This has worked in the past, but seems to be failing when the generic host starts. My endpoint configuration is below, along with the app.config for the service. What is strange is that in my endpoint configuration, I am specifying to use the XmlSerializer for message serialization. I don't see any other errors in the console output preceding the error message. What am I missing?
Thanks, Steve
