I'm looking to register an EasyNetQ's IBus which implements IDisposable as a singleton with StructureMap.
The issue is when using nested container, the instance is disposed with the container, thus leaving me with a singleton instance being disposed for every other containers.

For<IBus>()
    .Use(c => BusBuilder.CreateMessageBus())
    .Singleton();

ContainerScoped is not an option here as I need that is kept alive during all the application lifespan.

How do I prevent StructureMap from disposing this instance with nested containers ? How do I tell it to dispose the instance only with the root container ?

I knew something was odd with my issue. What was the point of defining singletons if they were disposed with each container ?

Indeed, StructureMap does not dispose singleton objects unless a root container is being disposed, see the PipelineGrap.cs source code. :

if (Role == ContainerRole.Root)
{
    _profiles.AllProfiles().Each(x => x.Dispose());
}

It turned out that my IBus instance was being manually disposed by some mysterious legacy code in which it was injected.

Anyway, for anyone facing the same issue : track down your call to Dispose as StructureMap is doing its job as you though it would :)
