Now that I'm developing in .NET 4.0 I thought all my covariance Buy Rimonabant (Acomplia) Without Prescription, problems were behind me. This was until I tried to use the following:

[csharp]

public class  Animal {
public void AttackOtherAnimals(IList<Animal> animals) { }
}

public class Dog : Animal { }

Dog angryDog = new Dog();
List dogsToAttack = new List<Dog>();
angryDog.AttackOtherAnimals(dogsToAttack);
[/csharp]
