How to remove(unregister) registered instance from Unity mapping?

Question

I meet one problem that i can't solve now. I have the following:

UnityHelper.DefaultContainer.RegisterInstance(typeof(IMyInterface), "test", instance); 

where UnityHelper.DefaultContainer is my helper for getting unity container with loaded configuration.

here I registered instance as an instance of IMyInterface.

So anywhere( some time after using) I want to remove this mapping. Remove it at all. How I can do it?

I have tried:

UnityHelper.DefaultContainer.Teardown(instance) 

but is was unsuccessful and the following code returns instance anyway:

UnityHelper.DefaultContainer.ResolveAll<IMyInterface>()

I had the same problem and just removed the registrations of the ContainerControlledLifetimeManager from my Container:

foreach (var registration in container.Registrations     .Where(p => p.RegisteredType == typeof(object)                 && p.Name == name                 && p.LifetimeManager.Type == typeof(ContainerControlledLifetimeManager))) {     registration.LifetimeManager.RemoveValue(); }

I think that is what you are looking for.

var lifetimeManager = new TransientLifetimeManager(); UnityHelper.DefaultContainer.RegisterInstance(typeof(IMyInterface), "test", instance, lifetimeManager); lifetimeManager.RemoveValue();
