sql-server - CodeFirst : Cannot open database "MyDatabase " requested by the login. 登录失败。用户 'MyDomain\MyUser' 登录失败

Question

所以我突然收到这个错误，我不知道如何解决它。 MyDomain\MyUser 列在服务器用户下，但由于我使用的是 CodeFIrst，数据库尚未创建，所以我无法将 MyDatabase 添加到用户。

这是我的代码:

连接字符串:

<add name="MyDatabaseConnection" connectionString="Data Source=myServer; Database=MyDatabase.sdf;Trusted_Connection=True;Persist Security Info=True;Pooling=false" providerName="System.Data.SqlClient" />

代码:

public class MyDbContext: DbContext
{
    public MyDbContext()
        : base("MyDatabaseConnection")
    {
    }

    public DbSet<User> Users { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.Configurations.Add(new UserConfiguration());
    }
}


public class UserConfiguration : EntityTypeConfiguration<User>
{
    public UserConfiguration()
    {
        ToTable("User");
        Property(u => u.ID).HasColumnName("UserID").HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
    }
}


protected void Application_Start()
{
    Database.SetInitializer<MyDbContext>(new MyDbContextInitializer());
    using (MyDbContext db = new MyDbContext())
    {
        db.Database.Initialize(false);
    }
    ...
}

public class MyDbContextInitializer : DropCreateDatabaseIfModelChanges<MyDbContext>
{
    protected override void Seed(MyDbContextcontext)
    {
        base.Seed(context);
        SeedMembership();
    }

    private void SeedMembership()
    {
        WebSecurity.InitializeDatabaseConnection(ConfigurationManager.ConnectionStrings["MyDatabaseConnection"].ConnectionString, "System.Data.SqlClient", "User", "UserID", "UserName", true);
        WebSecurity.CreateUserAndAccount("doe1", "password11", new { FirstName = "John", LastName = "Doe" });
    }
}
