AspIdentiy ApplicationUserManager是静态的，如何扩展，因此参与我的IoC框架？

问题描述

在新的ASPNET MVC应用程序你现在得到AspIdentity东西是免费的。

In a new ASPNET MVC application you now get the AspIdentity goodies for free.

有一个无伤大雅的小线在您的电子邮件服务在这里插件。

There's a harmless little line 'plug in your email service here'.

所以，我所做的：

public class EmailService : IIdentityMessageService
{
    private static My.Services.IEmailService _emailservice;

    public EmailService(Insolvency.Services.IEmailService emailservice)
    {
        _emailservice = emailservice;
    }

    public Task SendAsync(IdentityMessage message)
    {
        _emailservice.SendEmail(message);
       return Task.FromResult(0);
    }
}

和现在的喜悦：

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    private My.Services.IEmailService _emailservice;

    public ApplicationUserManager(IUserStore<ApplicationUser> store, My.Services.IEmailService emailservice): base(store)        
    {
        _emailservice = emailservice;
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
    {
        var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()), _emailservice);
       ...

在它Owin踢会调用在ApplicationUserManager创建 Startup.Auth.cs

public partial class Startup 
   {
    public void ConfigureAuth(IAppBuilder app) 
     {
        ...
        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);

和我敢用AutoFac作为我IoC容器中的global.asax.cs

and as I'm using AutoFac as my IoC container, in global.asax.cs

builder.RegisterType<My.Services.EmailService>().As<IEmailService>();

如果创建方法是静态的，所以我得到：结果
_emailService 为空

if the Create method is static so I get:
_emailService is null

我在这里看：和How做我创建的UserManager的和Using Autofac提供由静态工厂出口类型。
但没有运气。

I've looked here:http://forums.asp.net/post/5293670.aspx, and How do i create an instance of UserManager and Using Autofac to provide types exported by static factory.but no luck.

如果我更改：

private My.Services.IEmailService _emailservice;

是公共的非静态，​​我觉得国际奥委会神摇头，我不能建设所需的对象引用

to be public non-static I feel IoC gods shaking their heads, and I can't build 'object reference required'

推荐答案

今天，我用同样的问题（它仍然在工作，因为我是新来的Asp.Identity）挣扎。
我就是这么做的：

Today I was struggling with the same issue (still working on it since I'm new to Asp.Identity).I did it this way:

1. Startup.cs（使用自己的容器）

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        var authConfigurator = new AuthConfigurator();
        authConfigurator.ConfigureAuth(app);
        var unityContainer = UnityConfig<MvcUnityDependencyContainer>.UseContainer();
        //Asp identity registration
        IDataProtectionProvider dataProtectionProvider = app.GetDataProtectionProvider();
        unityContainer.RegisterInstance(dataProtectionProvider);
        unityContainer.RegisterType<DbContext, ApplicationDbContext>(new HierarchicalLifetimeManager());
        unityContainer.RegisterType<UserManager<ApplicationUser, int>>(new HierarchicalLifetimeManager());
        unityContainer.RegisterType IIdentityMessageService, EmailService>();
        unityContainer.RegisterType<IUserStore<ApplicationUser, int>,
            UserStore<ApplicationUser, CustomRole, int, CustomUserLogin, CustomUserRole, CustomUserClaim>>(
            new InjectionConstructor(new ApplicationDbContext()));
        unityContainer.RegisterType<IIdentityMessageService, EmailService>();
    }
}

ApplicationUserManager（我删除静态方法创建）：

public class ApplicationUserManagerService : UserManager<ApplicationUser, int>
{
    public ApplicationUserManagerService(IUserStore<ApplicationUser, int> store, 
                                         IIdentityMessageService emailService,
                                         IDataProtectionProvider dataProtectionProvider)
                                         : base(store)
    {
        UserTokenProvider = new EmailTokenProvider<ApplicationUser, int>();
        EmailService = emailService;
        Configure(dataProtectionProvider);
    }
    private void Configure(IDataProtectionProvider dataProtectionProvider)
    {
        // Configure validation logic for usernames
        UserValidator = new UserValidator<ApplicationUser, int>(this)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };
        // Configure validation logic for passwords
        PasswordValidator = new PasswordValidator
        {
            RequiredLength = 1,
            RequireNonLetterOrDigit = false,
            RequireDigit = false,
            RequireLowercase = false,
            RequireUppercase = false,
        };
        // Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user
        // You can write your own provider and plug in here.
        RegisterTwoFactorProvider("PhoneCode", new PhoneNumberTokenProvider<ApplicationUser, int>
        {
            MessageFormat = "Your security code is: {0}"
        });
        RegisterTwoFactorProvider("EmailCode", new EmailTokenProvider<ApplicationUser, int>
        {
            Subject = "Security Code",
            BodyFormat = "Your security code is: {0}"
        });
        if (dataProtectionProvider != null)
        {
            UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser, int>(dataProtectionProvider.Create("ASP.NET Identity"));
        }
    }
}

控制器

public class AccountController : Controller
{
    private ApplicationUserManagerService _userManagerService;
    public AccountController(ApplicationUserManagerService userManagerService)
    {
        Contract.Requires(userManagerService != null);
        _userManagerService = userManagerService;
    }
    /*....*/
}

ApplicationUser

public class ApplicationUser : IdentityUser<int, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, int> manager)
    {
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        return userIdentity;
    }
}

public class CustomRole : IdentityRole<int, CustomUserRole>
{
    public CustomRole() { }
    public CustomRole(string name) { Name = name; }
}

public class CustomUserClaim : IdentityUserClaim<int> { }
public class CustomUserLogin : IdentityUserLogin<int> { }
public class CustomUserRole : IdentityUserRole<int> { }

这对我的作品，但请随时提出更好的解决方案。

This works for me but please feel free to suggest better solution.
