Question

Is it possible to extend this interface? I’ve seen it’s possible, but I dont really understand how it works, I’d like to see the documentaiton on that, I saw someone made a class “IDbConnecitonExtension” or something like that and just magically worked.

Is it possible to extend this interface?

Yes. You extend it just like any other type.

public static class IDbConnectionExtensions {
    public static void MyExtension(this IDbConnection connection) {
        Console.WriteLine("Hello, connection!");
    }
}
