In order to obtain or modify this parameter, access the OpcLabs.EasyOpc.UA.Engine.UAClientServerApplicationParameters.ApplicationManifest property of OpcLabs.EasyOpc.UA.Application.EasyUAApplicationCore.ApplicationParameters property of static EasyUAApplication.Instance.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
