Question

当我在Visual Studio 2013中创建MVC 5应用程序，并选择个人帐户作为身份验证时，脚手架会自动配置ASP Net Identity。它会与ApplicationDbContext和ApplicationUserManager一起创建多个类。它还使用OWIN上下文注册这些类，如下所示，每个请求使用单个实例。

 public void ConfigureAuth(IAppBuilder app)
 {
        // Configure the db context, user manager and signin manager to use a single instance per request
        app.CreatePerOwinContext(ApplicationDbContext.Create);
        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
        app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);

 }

基本上它会注册每个类的static Create方法。这个静态方法负责创建该类的实例。

Quesion
1＆gt;如果我不想使用静态创建方法，下面的方法是否正确？

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>
{
    public ApplicationDbContext(string connString)
        : base(connString)
    {
    }
}

public void ConfigureAuth(IAppBuilder app)
{
   var conString = ConfigurationManager.ConnectionStrings["Myconnection"].ConnectionString
    app.CreatePerOwinContext(()=>new ApplicationDbContext(conString));
}

2 - ;如何在不使用静态Create方法的情况下注册ApplicationUserManager。（必须设置UserValidator，PasswordValidator，UserTokenProvider等）我应该在ApplicationUserManager的构造函数中设置Validators和UserTokenProvider吗？如下所示

public class ApplicationUserManager : UserManager<ApplicationUser, string>
{
     public ApplicationUserManager(ApplicationUserStore store)
        : base(store)
    {
        base.UserValidator = new UserValidator<ApplicationUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };

        // Configure validation logic for passwords
        base.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = true,
            RequireDigit = true,
            RequireLowercase = true,
            RequireUppercase = true,
        };

        base.EmailService = new EmailService();

        //?????????How do I get options.DataProtectionProvider ??????
        var dataProtectionProvider = options.DataProtectionProvider;
        if (dataProtectionProvider != null)
        {
            base.UserTokenProvider = 
                new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
        }
  }

3＆gt;在上面的方法中如何向OWIN上下文注册ApplicationUserManager以便它为每个请求创建单个实例？ 'ApplicationUserManager还需要ApplicationUserStore和ApplicationDbContext ..如何将这些传递给ApplicationUserManager的构造函数？

如何在OWIN上下文中注册UserManager？
