 Why does a windows service, hosting an NserviceBus endpoint in NServiceBus.Host.exe, fail to start when there are NO err

With these it helps The most common reason that I've found for this is down to logging.
The user account running the service must have Performance Monitoring Access.

 NServiceBus & IoT - place a message from client directly in queue and process with NServiceBus at server side

wish helps you You didn't mention what's your Transport, if you're trying to just Send a message to a destination or Publish an event? Some of these choices might change the answer here, but you should get a gist of it. You can integrate with NServiceBus directly by putting messages into the queue. If you look at the documentation you'll see there is 'Scripting' section under each transport which shows you how to put messages directly into the queue. If you want to integrate with MSMQ you can find the documentation page here. code :
public static void SendMessage(string queuePath, string messageBody, List<HeaderInfo> headers)
{
using (var scope = new TransactionScope())
{
using (var queue = new MessageQueue(queuePath))
using (Message message = new Message())
{
message.BodyStream = new MemoryStream(Encoding.UTF8.GetBytes(messageBody));
message.Extension = CreateHeaders(headers);
queue.Send(message, MessageQueueTransactionType.Automatic);
}
scope.Complete();
}
}
public static byte[] CreateHeaders(List<HeaderInfo> headerInfos)
{
XmlSerializer serializer = new XmlSerializer(typeof(List<HeaderInfo>));
using (var stream = new MemoryStream())
{
serializer.Serialize(stream, headerInfos);
return stream.ToArray();
}
}
public class HeaderInfo
{
public string Key { get; set; }
public string Value { get; set; }
}

NServiceBus 5.x to 6.x: NServiceBus.Host 7.0.1 + NServiceBus.Wcf = ambiguous type

it fixes the issue I found the issue. When converting our endpointconfig.cs files, I forgot to call our extension method that sets up the command/event conventions for discovery. No discovered commands = No Wcf Service.
P.S. The NSB team updated their conversion docs to include the aliasing steps. If you're converting and using the host to handle WcfServices, you'll have to use the alias, but I can confirm it will work correctly.

 NServiceBus Publish/Subscribe Example -- Couldnt load assembly NServiceBus.Core or its dependency

it helps some times In .NET 4, there are restrictions on running "unfamiliar" assemblies. You will probably need to add a NServiceBus.Host.exe.config with the following which will allow the assemblies to run:
