.NET6 Dependency Injection — One Interface, Multiple Implementations

You want to have multiple implementations with the same interface. In this article, I will show you how.

Multiple implementations with generic

I have the interface IMovivement with a method string Walk();

public interface IMoviment<T> where T : class
{
string Walk();
}

One friendly approach could be using an Enum for the generic T. But you cant do it. Language limitation, but probably in the future, C# allows you to do it.

public interface IMoviment<T> where T : MovimentEnum
{
string Walk();
}

This interface has three implementations, Cat, Dog, and Human class.

public class Dog : IMoviment<Dog>
{
public string Walk()
{
return “Im a Dog, walking!”;
}
}
public class Cat : IMoviment<Cat>
{
public string Walk()
{
