EROSessionNotFound

Overview

This exception is raised by servers requiring authentication, for example implemented using the Remoting SDK standard authentication pattern, to indicate that no session exists on the server yet, and a login is needed. This can happen automatically, when the RequiresSession property of a remote service is set, or manually, as needed. Client channels have special logic in place to catch this exception and fire a OnLoginNeeded event, which can be handled to perform a login on the fly and restart the failed request.

Please refer to the Authentication and Login topic for a more detailed exploration of the login and authentication mechanisms used by the Remoting SDK.
