AppDomain Unload killing Parent AppDomain

Question

I am having trouble figuring something out about my AppDomain.Unload(...) call. I have a detailed explanation with code from my earlier question. As it turns ou

As I suspected, instancing with the IModule interface in the primary domain causes a leak. In order to do this properly:

AppDomain domain = AppDomain.CreateDomain(domainName);
HostDomains[domainName] = domain;  // put in collection

ModuleAdapter adapter = (ModuleAdapter)domain.CreateInstanceAndUnwrap(asmName , typeName);

where ModuleAdapter inherits MarshalByRefObject. Then:

adapter.Execute(moduleAssembly , moduleType);

Inside the ModuleAdapter class:

public void Execute(string Name, string EntryPoint)
{
    module  = (IModule)AppDomain.CurrentDomain.CreateInstanceAndUnwrap(Name , EntryPoint);
}

I do welcome comments or additional answers for a better way.

After moving the instancing to the ModuleAdapter class, we are still having the issue with AppDomain.Unload killing the entire application. I was wondering if this is because in the module plugin we are using Application.Run(myForm) - then when we shutdown we call myForm.Close(). Obviously this shuts down the application so I was wondering if the myForm.Close() also 'unloads' the AppDomain.
