我已经在StackOverflow上回顾了几个这样的答案，我已经应用并比较了我的具体情况没有答案。以下是我的观点：
*****在Web.Config *****
<add name="DefaultConnection" connectionString="Data Source=LAPTOP-2UA8GL6L\SQLEXPRESS;Initial Catalog=FHSF_DEV;Integrated Security=True" providerName="System.Data.SqlClient" />
public class ApplicationUser : IdentityUser
{
public DateTime BirthDate { get; set; }
public string City { get; set; }
public string State { get; set; }
public int UserDetailID { get; set; }
public ClaimsIdentity GenerateUserIdentity(ApplicationUserManager manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = manager.CreateIdentity(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
public Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager manager)
{
return Task.FromResult(GenerateUserIdentity(manager));
}
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
}
}
在IdentityConfig.cs中
public class EmailService : IIdentityMessageService
{
public Task SendAsync(IdentityMessage message)
{
// Plug in your email service here to send an email.
return Task.FromResult(0);
}
}
public class SmsService : IIdentityMessageService
{
public Task SendAsync(IdentityMessage message)
{
// Plug in your SMS service here to send a text message.
return Task.FromResult(0);
}
}
// Configure the application user manager used in this application. UserManager is defined in ASP.NET Identity and is used by the application.
public class ApplicationUserManager : UserManager<ApplicationUser>
{
public ApplicationUserManager(IUserStore<ApplicationUser> store)
: base(store)
{
}
public class ApplicationUserManager : UserManager<ApplicationUser>
{
public ApplicationUserManager(IUserStore<ApplicationUser> store)
: base(store)
{
}
public class ApplicationDbContext : IdentityDbContext
{
public ApplicationDbContext()
: base("DefaultConnection")
{
}
public DbSet<ApplicationUser> ApplicationUsers { get; set; }
}
//////// Commented out the rest of the code within this class //////
public static ApplicationUserManager Create（IdentityFactoryOptions选项，IOwinContext上下文） { var manager = new ApplicationUserManager（new UserStore（context.Get（）））; //配置用户名的验证逻辑 manager.UserValidator = new UserValidator（manager） { AllowOnlyAlphanumericUserNames = false， RequireUniqueEmail = true };
// Configure validation logic for passwords
manager.PasswordValidator = new PasswordValidator
{
RequiredLength = 6,
RequireNonLetterOrDigit = true,
RequireDigit = true,
RequireLowercase = true,
RequireUppercase = true,
};
// 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 it in here.
//manager.RegisterTwoFactorProvider("Phone Code", new PhoneNumberTokenProvider<ApplicationUser>
//{
// MessageFormat = "Your security code is {0}"
//});
//manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser>
//{
// Subject = "Security Code",
// BodyFormat = "Your security code is {0}"
//});
// Configure user lockout defaults
manager.UserLockoutEnabledByDefault = false;
manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
manager.MaxFailedAccessAttemptsBeforeLockout = 5;
manager.EmailService = new EmailService();
manager.SmsService = new SmsService();
var dataProtectionProvider = options.DataProtectionProvider;
if (dataProtectionProvider != null)
{
manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
}
return manager;
}
}
并且，在发生错误的调用程序中
if (IsValid)
{
// Validate the user's email address
//var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
//ApplicationUser user = manager.FindByName(Email.Text);
/////////////////////////////////////////////////////////////////
//var userStore = new UserStore<IdentityUser>();
//var userManager = new UserManager<IdentityUser>(userStore);
//IdentityUser user = userManager.FindByEmail(Email.Text);
var provider = new DpapiDataProtectionProvider("FHSFReset");
ApplicationDbContext context = ApplicationDbContext.Create();
var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>());
///////////////////////////////////////////////////////////
// The error occurs below /////////////////////////////////
///////////////////////////////////////////////////////////
ApplicationUser user = userManager.FindByEmail(Email.Text);
///////////////////////////////////////////////////////////
// Error msg: System.InvalidOperationException: 'The entity
// type ApplicationUser is not part of the model for the
// current context.'
///////////////////////////////////////////////////////////
if (user == null)
{
FailureText.Text = "The user either does not exist or is not confirmed.";
ErrorMessage.Visible = true;
return;
}
// For more information on how to enable account confirmation and password reset please visit https://go.microsoft.com/fwlink/?LinkID=320771
// Send email with the code and the redirect to reset password page
userManager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
provider.Create("EmailRestPW"));
注意：我正在使用身份，实体框架（我认为）和OWIN。我试图在我的数据库中保留授权/身份验证表，表格就在那里。我（如上所示）在AspNetUsers中添加了自定义字段，应该反映在连接中。
有没有明显的迹象表明我已经错误地设置了这个，以便发生错误？
