C # alternative to abstract

How to make derived forms implement the methods of the base class without making it abstract?

Received error: "The designer must create an instance of type" X ", but he cannot, because the type is declared as abstract." Thank you in advance.

I would create an interface so that each form can implement it. Could you tell us more about your problem?

You cannot force a class to override a base class method unless it is marked abstract, which also requires the base class to be abstract. Have you thought about defining an interface for these methods?

public class PyramidenMain extends ProbabilityGame implements IProbabilityGame{
    public function PyramidenMain(){
        super(this);
        super.initialize();
    }   

    //implement interface
}

public interface IProbabilityGame{
        function getGame():MovieClip;
        function customInit():void;
        function customLoginSuccessful():void;
        function customLoginError(xml:XML):void;
        function customShowError(msg:String):void;
        function createDemoProtocol():IProtocol;
    }

public class ProbabilityGame {
    public function ProbabilityGame(game:IProbabilityGame) {
        if(game == null) {
            throw new Exception("unmet requirement, parameter containing an instance of IProbabilityGame");
        }
        _game = game;
    }

    public function initialize() {
        //do some logic
        _game.customInit();
    }
}

You can override the base class and define abstract or virtual methods. Perhaps this is what you want. This is reality in a work environment.
