For .NET Open Clients, the supported application server operating modes are the session-managed and the session-free modes. For more information, see the information on session models in the topic on generating proxies and Web service definitions in Learn About Open Clients.

To access a session-free application server, you must set the proxy property PROGRESS.Session.SessionModel to 1. For more information, see Access Proxy Properties.

ReleaseConnection

For session-free applications, you must explicitly release the connections held by a Connection object when they are no longer needed. Use the following method on the Connection object for this purpose:

public void ReleaseConnection( )
Note: This method is not necessary for and has no effect in session-managed applications.
