MVC 5 Exception de délai d'attente d'autorisation d'utilisation lors de l'utilisation avec TransactionScope

Question

Je souhaite utiliser MVC 5 Identity pour l'appartenance. Et je dois utiliser ADO.Net avec TransactionScope pour toutes les autres transactions de base de données. Dans une méthode, j'ai besoin d'utiliser Identity et TransactionScope ensemble. Mais si j'utilise TransactionScope, Create() méthode jeter une exception de délai d'expiration expiré en environ 10 secondes. Quelqu'un sait-il pourquoi? Voici le contenu de la méthode mentionnée;

public void CreateUser(string password) { 
    var userManager = new MyUserManager(new UserStore<ApplicationUser>(new ApplicationDbContext())); 

    using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, new TimeSpan(0, 30, 0))) 
    { 
     var company = new Company() { 
      Id = Guid.NewGuid(), 
      Name = "Cmp1" 
     }; 

     AddCompany(company); 

     var user = new ApplicationUser() 
     { 
      UserName = "Usr1", 
      CompanyId = company.Id 
      //... Other Properties ... 
     }; 

     userManager.Create(user, password); // The exception is thrown right there. 
     scope.Complete(); 
    } 
} 

public void AddCompany(Company company) 
{ 
    using (SqlConnection connection = new SqlConnection(CONN)) 
    { 
     SqlCommand command = new SqlCommand(); 

     command.Connection = connection; 
     command.CommandText = "INSERT INTO Companies values(@Id, @Name)"; 

     command.Parameters.AddWithValue("@Name", company.Name); 
     command.Parameters.AddWithValue("@Id", company.Id); 

     connection.Open(); 
     command.ExecuteNonQuery(); 
     connection.Close(); 
    } 
}
