Autofac Parent class and child class implementing same Interface
Multi tool use
I want to resolve a parent class which takes a child class as a parameter and both implements the same interface.
How should I go about writing the AutoFac bootstrap file to resolve the EmailNotifier?
When I try to resolve I get the circular dependency error. Following is the code. I Already tried builder.RegisterAssemblyTypes this brings only the child implementation
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Autofac;
namespace AutoFactTest
{
// This interface lets you send some content
// to a specified destination.
public interface ISender
{
string Send(string message);
}
// We can implement the interface for different
// "sending strategies":
public class PostalServiceSender : ISender
{
public string Send(string message)
{
return message;
}
}
public class EmailNotifier : ISender
{
ISender _postal;
public EmailNotifier(ISender postal)
{
_postal = postal;
}
public string Send(string message)
{
return "EMail " + message;
}
public string DoSomethingElse(string message)
{
return "Do Something Else with " + Send(message);
}
}
public class PostalModule : Module
{
protected override void Load(ContainerBuilder builder)
{
builder.RegisterType<PostalServiceSender>().AsSelf().As<ISender>().InstancePerDependency();
}
}
public class EmailModule : Module
{
protected override void Load(ContainerBuilder builder)
{
builder.RegisterModule<PostalModule>();
builder.RegisterType<EmailNotifier>().AsSelf().As<ISender>().InstancePerDependency();
}
}
class Program
{
static void Main(string args)
{
var builder = new ContainerBuilder();
builder.RegisterModule<EmailModule>();
//This doesn't work because it takes only child implementation
// builder.RegisterAssemblyTypes(typeof(EmailNotifier).Assembly)
//.Where(x => x.Name.EndsWith("Sender"))
//.AsImplementedInterfaces();
var container = builder.Build();
ISender sender = container.Resolve<ISender>();
var output = container.Resolve<EmailNotifier>(new Autofac.NamedParameter("postal", sender));
}
}
}

This looks straight out of the FAQ which has concrete suggestions... Like not having the same interface mean two different things. What have you tried so far? Please update the question with this info rather than respond here in comments.
