How can I extend a Unity catalog at runtime?

Question

I want to map most of my interfaces to concrete classes in my app.config file. However, I would like to register some interfaces to the same Unity catalog at runtime. I tried the code below, but it gives me a SynchronizationLockException: Object synchronization method was called from an unsynchronized block of code.

IUnityContainer container = new UnityContainer();

UnityConfigurationSection configSection =
    (UnityConfigurationSection)ConfigurationManager.GetSection("unity");
configSection.Containers.Default.Configure(container);

container.RegisterInstance<IInterface>(new ConcreteObject());

How can I register an object at runtime in a Unity catalog initialized from app.config?

I am using the Unity version (2.0) that ships with Prism4.

This is a common problem, but not technically an error, with registering unity objects. Change your regsitration to this:

container.RegisterType<IInterface, ConcreteObject>(new ContainerControlledLifetimeManager());

That should fix your problem.

That exception gets thrown because of this:

Can Unity be made to not throw SynchronizationLockException all the time?

Thanks for the pointer, but how do I pass in the object instance? – MvdD Mar 31 '11 at 16:56
That should create the instance for you when you ask for it. – poindexter12 Mar 31 '11 at 17:05

yes, but I do not want it to new up a new instance. I want it to return an instance I register with the container at runtime. – MvdD Mar 31 '11 at 19:24
