public interface IHamster
{
    int Some { get; set; }
}

public abstract class BaseHamster : IHamster
{
    public int Some { get; set; }
}

public class DerivedHamster : BaseHamster
{
}

class ApplyHitHamster<T> where T : IHamster   // <-- same constraint 
{
    void Zu()
    {
        BaseHamster hamster = null;
        var derived = new DerivedHamster();
        IHamster i = derived;

        var s = new TakeDamageHamster<T>(i); // <<<< Compilation Error on any variables(hamster,derived,i) WHY?????????
        var s2 = new TakeDamageHamster<IHamster>(i); …
