Проблемы миграции миграции ASP.NET с MySQL и EF6

Question

Я использую MVC5, EF6 с кодовым кодом, MySql, и у меня не было проблем с выполнением миграции для создания базы данных, и все работает нормально. Теперь я хочу использовать ASP.NET Identity для управления моими пользователями, поэтому я добавил необходимые пакеты Nuget в проект Data Acess. Когда я бегу 'Enable-миграции' в Package Manager Console я получаю следующее:

Я не сделал измените любые настройки, я только что удалил предыдущую папку миграций, которая была создана до добавления идентификатора ASP.NET в качестве зависимости. У кого-то еще была такая же или подобная проблема?

IdentityModels:

public class User:IdentityUser 
{ 
     public string FirstName { get; set; } 
     public string LastName { get; set; } 
     public int StudentNumber { get; set; } 
} 

DbContext класса

public class SolutionContext:IdentityDbContext<User> 
{ 
     public DbSet<LanguageTest> LanguageTests { get; set; } 
     public DbSet<Certificate> Certificates { get; set; } 
} 

Answer 1

Я думаю, что проблема здесь заключается в том, что ваш SolutionContext отсутствует его конструктор по умолчанию и метод Create.

Вы должны изменить свой SolutionContext, чтобы выглядеть следующим образом:

public class SolutionContext: IdentityDbContext<User> 
{ 
    public DbSet<LanguageTest> LanguageTests { get; set; } 
    public DbSet<Certificate> Certificates { get; set; } 

    public SolutionContext() 
     : base("SolutionContext", throwIfV1Schema: false) 
    { 
    } 

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