With these it helps Polymorphism is a property of classes, in that they implement a common interface, or are derived from a base class, implementing virtual methods in a different way to reflect the different behavior of derived classes.
Generics is a property of an algorithm, or a class implementing an algorithm (sort) or a common operation (lists), requiring the classes they deal with to have certain methods, properties, or interfaces.

will help you Note: In all cases, you will have to initialize the Contents field to a concrete object that implements IList
When you keep the generic constraint, you can do:
code :
public IList<T> Contents = new List<T>();
public IList<MyInterface> Contents = new List<MyInterface>();
public void CallAllMethodsInContainer<T>(MyContainer<T> container) where T : IMyInterface
{
    foreach (T myClass in container.Contents)
    {
        myClass.MyMethod();
    }
}
MyContainer<MyClass> container = new MyContainer<MyClass>();
container.Contents.Add(new MyClass());
this.CallAllMethodsInContainer(container);
public void CallAllMyMethodsInContents()
    {
        foreach (T myClass in Contents)
        {
            myClass.MyMethod();
        }
    }
MyContainer<MyClass> container = new MyContainer<MyClass>();
container.Contents.Add(new MyClass());
container.CallAllMyMethodsInContents();
public class MyContainer
{
    public IList<MyInterface> Contents;
}
  public void CallAllMethodsInContainer(MyContainer container)
MyContainer container = new MyContainer();
container.Contents.Add(new MyClass());
this.CallAllMethodsInContainer(container);

wish helps you Without a simpler and yet more-complete code example, it's impossible to provide specific advice in your specific scenario. However, the basic problem is that the types are indeed not convertible, just as the compiler says.
Why can I not convert TagSystem to AComponentSystem? This seems like a valid morph.

I hope this helps . Generics
What you see here are generics. It has nothing to do with polymorphism.
code :
public static void foo(int bar) { ... }
foo(5);
foo(8);
public class Pair<A, B> { ... }
Pair<String, Integer> stringAndInteger;
Pair<Dog, Car> dogAndCar;
public void setFirst(A first) { ... }
public class Animal {
    public void makeNoise() {
        System.out.println("Hello");
    }
}
public class Dog extends Animal {
    @Override
    public void makeNoise() {
        System.out.println("wuff wuff");
    }

    public String getName() {
        return "John";
    }
}

To fix this issue The problem is that you have defined tableImpl with the type CellTable.
? extends Model means "some specific subclass of Model, but I am not sure what it is".
why polymorphism not applicable with generics?
