How to check if remoted object is present?

Hi,

If I connect to a remoted object using RemotingServices.Connect, then a
TransparantProxy is returned even if the remoted object is not alive.

How can I check whether the remoted object is alive without having to call
a method in its remoted interface?

Thanks,

Yes, a proxy is returned but it's created by the client, not the server. No
communication with the server occurs during the call to
RemotingServices.Connect().

As you've discovered, you need to call a non-OneWay method on the object.

Is that a dummy-method I would have to write myself then? There is no methd
such as 'CheckConnection' or something?
