Autofac.cs

// Conventionally register types implementing a single I[Classname] interface.
builder.RegisterAssemblyTypes(assemblies)
        .Where(x => x.GetInterfaces().Count() == 1 && x.GetInterface("I" + x.Name) != null)
        .AsImplementedInterfaces();

// Register types as themselves.
builder.RegisterAssemblyTypes(assemblies)
    .AsSelf();
