Injecting AutoMapper instance

Question

I have an ASP.NET MVC application with all mappings registered during the bootstrap in this way:

Mapper.CreateMap<AdvicesModel, Advices>();

So far we've used it the "old" way statically:

Mapper.Map<Advice>(adviceDto)

So far so good.

After the update to version 4 of AutoMapper I've seen that it is recommended to use it constructing an Instance. Can someone point me how to properly instruct Castle to Inject an instance of AutoMapper to my dependencies and user it not statically.

What I imagine is something like this:

var viewModel = mapper.Map<CartViewModel>(cart);

with IMapper instance injected.

I don't think services.AddSingleton<> is Castle Windsor so below is my CastleWindsor installer.

        private static void RegisterProfilesAndResolvers(IWindsorContainer container)
    {
        // register value resolvers
        container.Register(Types.FromAssembly(Assembly.GetExecutingAssembly()).BasedOn<IValueResolver>());

        // register profiles
        container.Register(Types.FromThisAssembly().BasedOn<Profile>().WithServiceBase().Configure(c => c.Named(c.Implementation.FullName)).LifestyleTransient());

        var profiles = container.ResolveAll<Profile>();

        var config = new MapperConfiguration(cfg =>
        {
            foreach (var profile in profiles)
            {
                cfg.AddProfile(profile);
            }
        });

        container.Register(Component.For<MapperConfiguration>()
            .UsingFactoryMethod(() => config));

        container.Register(
            Component.For<IMapper>().UsingFactoryMethod(ctx => ctx.Resolve<MapperConfiguration>().CreateMapper(ctx.Resolve)));
    }

I'm not sure if this is ideal/optimal etc but it does seem to work :-)
