Hi, How can i recieve derived class with WS-Man get operation? Enumerating class, for example CIM_X, return also the derived classes. What i'm trying to do is to get a derived class (using Get), i know i have one class so Get with specify keys should return me this class (but the resource uri is the resource uri of the base class). Is there any tag (wsman spec) that allow Polymorphism in get? Thanks
