MVC: Проблемы с подключением к базе данных

Question

У меня есть приложение только в asp.net mvc.

Я пытаюсь войти в приложение через твиттер

После того как пользователь входит в систему через твиттер (который он/она успешно делает) он попадает следующую строку в ExternalLoginConfirmation методом

// Get the information about the user from the external login provider 
       var info = await AuthenticationManager.GetExternalLoginInfoAsync(); 

После выше Lind выполняется в браузере, я получаю ошибку, которая говорит

Login failed for user ''. 

Это то, что StackTrace говорит Трассировка стека:

[SqlException (0x80131904): Login failed for user ''.]

Я предполагаю, что он не в состоянии подключиться к базе данных

У меня есть класс DbContext в DAL проекта

public class TwitterDbContext : IdentityDbContext<User>, ITwitterDbContext 
    { 
     public TwitterDbContext() 
      : base("TwitterContextConnection") 
     { 
     } 

     public static TwitterDbContext Create() 
     { 
      return new TwitterDbContext(); 
     } 

    } 

это моя строка соединения в web.config

<connectionStrings> 
    <add name="TwitterContextConnection" connectionString="Data Source=.\SQLEXPRESS;Database=Twitter Integrated Security=True" providerName="System.Data.SqlClient" /> 
    </connectionStrings> 

Я убеждался, что работает SQLEXPRESS. Я включил миграции для базы данных с помощью PackageManagerConsole и когда я пытаюсь обновить базу данных я получаю ошибку, которая говорит

This operation requires a connection to the 'master' database. Unable to create a connection to the 'master' database because the original database connection has been opened and credentials have been removed from the connection string. Supply an unopened connection. 

Есть ли что-то я делаю не так? База данных еще не существует, но я считаю, что она должна создаваться, когда она не существует.

Answer 1

Похоже, у вас есть ';' отсутствует между вашими значениями:

<connectionStrings> 
    <add name="TwitterContextConnection" connectionString="Data Source=.\SQLEXPRESS;Database=Twitter;Integrated Security=True";providerName="System.Data.SqlClient" /> 
</connectionStrings>
