Receiving MessageDeserialization Exception in NServiceBus

Question

I'm just getting refamiliarized with NServiceBus and I'm receiving a MessageDeserialization exception and stack trace as shown below.

For some environmental information... I'm using azure persistence with Queues. I can see the subscription table and what looks like all the endpoint addresses for my subscribers.

I have 3 MVC Web API hosted apps. The Service/API publishing the message that causes this exception is configured in its app.config to subscribe to itself and 2 other apis. The others that don't seem to have a problem have only 1 subscription. The first subscribes to one of its own events. And the other subscribes to 3 events from the 3rd service/api.

Things I've tried in order to resolve the issue. I was using conventions to define my events, but now my event messages all implement IEvent. I've also defined the JsonSerializer. Here's my bus configuration setup...

public class NServiceBusEndpointConfig : IConfigureThisEndpoint, AsA_Worker
{
    public static IBus bus;

    public void Customize(BusConfiguration busConfig)
    {
        var configuration = ContainerConfig.Container.Resolve<ICredentialDomainConfig>();

        busConfig.AzureConfigurationSource();
        busConfig.UseTransport<AzureStorageQueueTransport>()
            .ConnectionString(configuration.NServiceBusQueueConnectionString);
        busConfig.UsePersistence<AzureStoragePersistence>();
        busConfig.EndpointName("service1");

        busConfig.UseContainer<AutofacBuilder>(c => c.ExistingLifetimeScope(ContainerConfig.Container));
        busConfig.UseSerialization<JsonSerializer>();  
        busConfig.License(configuration.NServiceBusLicenseString);
    }
}

}

Here is the exception and stack trace details...

Here's the message class as requested... Originally there were 3 different "Infos" in the message, but tried to simplify, so now only the permission info in in the event...

  public class CredentialPermissionGrantedEvent : IEvent
    {
        public PermissionInfo Permission { get; set; }
    }    

public class PermissionInfo
    {
        public Guid PermissionReference { get; set; }
        public DateTime ActivationDate { get; set; }
        public Guid CredentialReference { get; set; }
        public Guid DeviceReference { get; set; }
        public DateTime ExpirationDate { get; set; }
        public string Function { get; set; }
        public Guid ScheduleReference { get; set; }
        public long Timestamp { get; set; }
    }

Any assistance will be greatly appreciated

Share your message class with us, Also, try using Xml serialization instead of Json, just to see if it will work. — Alexey Zimarev
Original Post has message class(es) added. Will try XML serializer, thanks — Paul Heal
Further points... If I manually drop the messages from the error queue into the subscription Queue the message is handled correctly. — Paul Heal
We had issues earlier with Json and Azure SB queues. Yves explained that we should use xml and json was not supported. I am not sure if this has changed but pls let me know what happens if you use xml serializer. Try omitting direct serializer specification, assuming the default one will be used. — Alexey Zimarev
Any luck with this issue? what was the solution? getting the same error — Mike

Looks like json.net is deserializing your message to a JObject instead of your message's type, do both endpoints know about the same type? If you look at the message body, is the necessary json.net metadata ($type) included?
