I am migrating a large codebase from Ninject to Autofac and am struggling on one of the bindings (that i believe is causing an activation error based on some of my debugging).

Ninject:

Bind<ISecureDataFormat<AuthenticationTicket>>()
     .ToMethod(context =>
         {
             var owinContext = context.Kernel.Get<IOwinContext>();
             return owinContext
                    .Get<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat");
         });

Autofac (what i have):

builder.Register(
    context => context.Resolve<IOwinContext>()
        .Get<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat"))
        .As<ISecureDataFormat<AuthenticationTicket>>();

Startup.cs:

var container = RegisterIoC(app, config);

public IContainer RegisterIoC(IAppBuilder app, HttpConfiguration config)
    {
        var builder = new ContainerBuilder();
        builder = RegisterDependencies(builder);
        builder = RegisterFilters(builder, config);

        /*builder.RegisterModule<DebuggingRequestModule>();*/

        var container = builder.Build();

        DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
        config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

        app.UseAutofacMiddleware(container);
        app.UseAutofacMvc();
        app.UseAutofacWebApi(config);
        app.UseWebApi(config);

        return container;
    }

More:

builder.RegisterModule<ApiDependencyModule>().RegisterModule<AutofacWebTypesModule>();
builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
builder.RegisterApiControllers(typeof(AccountController).Assembly);

(seemingly) associated constructors:

AccountController.cs:

public AccountController(ILoginService loginService,
                             IBearerTokenStore tokenStore,
                             IRememberMeCookieService rememberMeCookieService,
                             IInternalSsoChallenge ssoChallenge)
{
}

LoginService.cs:

public LoginService(IBearerTokenStore tokenStore, 
        IGrantTypeProvider grantProvider, 
        IRememberMeCookieService rememberMeCookieService)
{
}

BearerTokenCookieStore.cs:

public BearerTokenCookieStore(IOwinContext owinContext, ISecureDataFormat<AuthenticationTicket> secureDataFormat, IAppSettingsReader appSettingsReader, ICookieService cookieService)
{
}

I have a logging module that is helping me debug and this is the message list i have

Resolving  _______.Login.Controllers.AccountController
--Resolving  _______.ApiGateway.Services.Auth.LoginService

  • I did include that, both the ninject setup that used to work and the autofac one that is failing in the question.

    can you add your startup? are you using autofac for owin? did you add app.UseAutofac(container)?

  • @Mutmatt - can you include also your packages.xml (it is sufficient to include just owin/webapi/mvc/autofac dependencies). The thing that seems odd in startup is mixing MVC4-like bootstrapping with newer bootstrapping. Jun 7, 2018 at 4:32
  • We don't have a packages.xml file....

    Honestly, I should have answered this question while I still had the codebase in my possession. I'd have to find someone who still works at my previous employer to find the solution I ended up with. I believe I changed the structure of the injection

We can use autofac with those c# owin inversion-of-control (ninject to autofac) like below, genericly

Startup.cs

public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {

            var config = new HttpConfiguration();
            WebApiConfig.Register(config);    

            ConfigureIoC(app, config);
            Components.Config();

            Auth.ConfigureForApi(app);

            app.UseAutofacWebApi(config);
            app.UseCors(CorsOptions.AllowAll);
            app.UseWebApi(config);
            config.EnsureInitialized();
        }

        private void ConfigureIoC(IAppBuilder app, HttpConfiguration config)
        {
            IoC.RegisterModules(
                builder =>
                {
                    builder.Register<IAuthenticationManager>(c => c.Resolve<IOwinContext>().Authentication).InstancePerRequest();
                    builder.Register<IDataProtectionProvider>(c => app.GetDataProtectionProvider()).InstancePerRequest();
                    builder.RegisterApiControllers(typeof(Startup).Assembly).PropertiesAutowired();
                },
                container =>
                {
                    config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
                    app.UseAutofacMiddleware(container);

                },
                true
                );
        }

    }

WebApiConfig.cs

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

    }
}

Component config:

public static class Components
{
    public static void Config() {
        TypeAdapterConfig.GlobalSettings.AllowImplicitDestinationInheritance = true;
        var registers = new List<IRegister>();
        registers.Add(new DtoMapping());
        registers.Add(new MappingRegistration());
        TypeAdapterConfig.GlobalSettings.Apply(registers);

        ObjectMapper.Current = new MapsterAdapter();
        DbConfiguration.Loaded += DbConfiguration_Loaded;

        var r = new Registrations();
        r.Run();
    }


    private static void DbConfiguration_Loaded(object sender, System.Data.Entity.Infrastructure.DependencyResolution.DbConfigurationLoadedEventArgs e)
    {
        e.ReplaceService<DbProviderServices>((s, k) => System.Data.Entity.SqlServer.SqlProviderServices.Instance);
    }

}

Authentication:

public class Auth
    {
        public static void ConfigureForMvc(IAppBuilder app)
        {
            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Login"),

                Provider = new CookieAuthenticationProvider
                {
                    OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, UserEntity, int>(
                        validateInterval: TimeSpan.FromMinutes(30),
                        regenerateIdentityCallback: (manager, user) =>
                        user.GenerateUserIdentityAsync(manager, DefaultAuthenticationTypes.ApplicationCookie),
                        getUserIdCallback: (Identity) => Identity.GetUserId<int>())
                }
            });
        }

        public static void ConfigureForApi(IAppBuilder app)
        {
            var OAuthServerOptions = new OAuthAuthorizationServerOptions()
            {
                AllowInsecureHttp = true,
                TokenEndpointPath = new PathString("/oauth2/token"),
                AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(120),
                Provider = new CustomOAuthProvider(),
                AccessTokenFormat = new CustomJwtFormat(ConfigConstants.Issuer)
            };

            app.UseOAuthAuthorizationServer(OAuthServerOptions);

            app.UseJwtBearerAuthentication(
                new JwtBearerAuthenticationOptions
                {
                    AuthenticationMode = AuthenticationMode.Active,
                    AllowedAudiences = new[] { ConfigConstants.AudienceId },
                    IssuerSecurityTokenProviders = new IIssuerSecurityTokenProvider[]
                    {
                        new SymmetricKeyIssuerSecurityTokenProvider(ConfigConstants.Issuer, ConfigConstants.AudienceSecurityKey)
                    }
                });

        }
    }
