How can you add an already created instance to a MEF container/cataloge to use when resolving Imports. I want the functionality that Unity gives with the RegisterInstance method on its containers.

You can use the ComposeExportedValue function for this, like so:

var container = new CompositionContainer();

container..ComposeExportedValue<IConfigFileInvoker>(new ConfigFileInvoker());

container..ComposeExportedValue<IConfigFileInvoker>("export-string",new ConfigFileInvoker());
