Clinton,

When you call Connect, you are looking for a well-known object.
Well-known objects can either be single-call, or singleton. Each of these
modes require a parameterless constructor. The reason for this is that if
it is a singleton, then the instance will already be created when you call
it (the constructor doesn''t really do much in this case). In the case of
the single-call, the argument could be made that parameters could be passed,
however, the idea is that these are services, that are running whether you
create them or not, so you constructing a new object in the service doesn''t
make sense.

If you want a model where you can pass the parameters to the
constructor, then I would use a client-activated object, which requires you
to register the type on the client and the server through the static
RegisterActivatedClientType and RegisterActivatedServiceType methods on the
RemotingConfiguration class.

Hope this helps.
