    NServiceBus.Host.exe is for running an endpoint all by itself, and provides the means to easily install an endpoint as a Windows service.

    If you are trying to embed NServiceBus within a Windows Forms app, then the WinForms exe needs to be the “host”. Do not reference NServiceBus.Host.exe. Only reference NServiceBus.dll and NServiceBus.Core.dll. (And log4net.dll probably as well.)

    Within the startup of your WinForms app, you will need to manually initialize the Bus, as described here.

    This, at least, is the general pattern for using NServiceBus within a Windows Forms app. I have not specifically tried releasing an app like that with ClickOnce. I’m not sure if ClickOnce can take care of the MSMQ dependency or not.
