To do this with CAOs you create an SAO object factory that instantiates and
returns your CAOs. For example, say you have an object which will be
client-activated and for which you've defined an interface that will be in
your shared assembly:
public class MyCAO : MarshalByRefObject, IMyCAO
{
// ...
}
Then create an SAO factory as follows:
public class CAOFactory : MarshalByRefObject, ICAOFactory
{
// Function to create your CAO object
public IMyCAO CreateCAO()
{
return new MyCAO();
}
}
In your client, you use Activator.GetObject() to get the SAO class factory,
then invoke the CreateCAO() method to get your CAO object reference. For
example,
ICAOFactory factory = (ICAOFactory) Activator.GetObject(typeof(ICAOFactory),
"tcp://...");
IMyCAO cao = factory.CreateCAO();
Using this technique you don't need the CAO's class definition on the
client, just the interface definitions.
