Basically, you just create the new AppDomain, and then call AppDomain.CreateInstanceAndUnwrap to create the type. Here's a simple CodeProject article about this process.

There are some tricks, here. You can't ever refer to the Type directly (this will load the type into your current AppDomain), and the objects should all derive from MarshallByRefObj. This will allow you to use the object "remotely", meaning keep it from loading into your AppDomain.
