Cannot implicitly convert derived type to its base generic type

Question

I have the following classes and interfaces:

public interface IThing
{
    string Name { get; }
}

public class Thing : IThing
{
    public string Name { get         


        

Answer 1

If you make ThingConsumer an interface rather than an abstract class, then your code will work as is.

public interface IThingConsumer where T : IThing
{
    string Name { get; set; }
}

Edit

One more change needed. In ThingConsumerFactory, cast back to the return type IThingConsumer:

return (IThingConsumer)new MyThingConsumer();
