Тип сущности ApplicationUser не является частью модели для текущего контекста.

Question

Пожалуйста, скажите мне, где моя работа не так:

Я разработал и закодировал свой проект с самого начала без идентификации. Позднее, при создании программы, мне нужно было добавить идентификацию в мой проект.и я создал таблицы идентификаторов в базе данных программы.когда я загружаю http://localhost/account/login и я ввожу адрес электронной почты и пароль в окне входа в систему и нажимаю кнопку «ОК» ، я сталкиваюсь со следующей ошибкой. Также эта ошибка возникает, когда я хочу зарегистрировать пользователя. Я также добавил следующее соединение к web.config:

<connectionStrings>
<add name="DefaultConnection" connectionString="metadata=res://*/Models.DomainModels.MachinaryModel.csdl|res://*/Models.DomainModels.MachinaryModel.ssdl|res://*/Models.DomainModels.MachinaryModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.\SQLEXPRESS2017;initial catalog=Machinary;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
<add name="MachinaryEntities" connectionString="metadata=res://*/Models.DomainModels.MachinaryModel.csdl|res://*/Models.DomainModels.MachinaryModel.ssdl|res://*/Models.DomainModels.MachinaryModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.\SQLEXPRESS2017;initial catalog=Machinary;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

Accountcontroler / Login:

 Public Async Function Login(model As LoginViewModel, returnUrl As String) As Task(Of ActionResult)
        If Not ModelState.IsValid Then
            Return View(model)
        End If

        ' This doesn't count login failures towards account lockout
        ' To enable password failures to trigger account lockout, change to shouldLockout := True
        Dim result = Await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout:=False)
        Select Case result
            Case SignInStatus.Success
                Return RedirectToLocal(returnUrl)
            Case SignInStatus.LockedOut
                Return View("Lockout")
            Case SignInStatus.RequiresVerification
                Return RedirectToAction("SendCode", New With {
                    returnUrl,
                    model.RememberMe
                })
            Case Else
                ModelState.AddModelError("", "Invalid login attempt.")
                Return View(model)
        End Select
    End Function
