SQLite没有创建DateTime字段

在我的c# VS2015 Windows 10通用应用程序中，我无法在数据库模式中创建DateTime字段。它会创建一个bigint。我还有其他表，它们创建了一个DateTime字段，没有问题。

这里有一个例子:(参见GameDate字段)

表[结果]领域:17(季):nvarchar (100)[Id]:整数[HomeTeamName]: nvarchar (100)[OppTeamName]: nvarchar (100)[GameDate]: datetime

Foreign Keys: 0
Indexes: 1
    [] PRIMARY
        [Id] AUTOINCREMENT 
Triggers: 0
Unique constraints: 0
Check constraints: 0

    private void AddUserButton_Click(object sender, RoutedEventArgs e)
    {
        User user = new User();
        user.Name = "User1";
        user.GameDate = Convert.ToDateTime("2015-09-02");
        var path = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "BaseBallOU.db");
        using (SQLite.Net.SQLiteConnection conn = new SQLite.Net.SQLiteConnection(new SQLite.Net.Platform.WinRT.SQLitePlatformWinRT(), path))
        {
            conn.Insert(user);
        }
    }
    private void CreateTablesButton_Click(object sender, RoutedEventArgs e)
    {
        var path = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "BaseBallOU.db");
        using (SQLite.Net.SQLiteConnection conn = new SQLite.Net.SQLiteConnection(new SQLite.Net.Platform.WinRT.SQLitePlatformWinRT(), path))
        {
            conn.CreateTable<User>();
            conn.CreateTable<TeamX>();
        }
    }
}
public class User
{
    [SQLite.AutoIncrement, SQLite.PrimaryKey]
    public int id { get; set; }
    public DateTime GameDate { get; set; }
    public string Name { get; set; }
}
public class TeamX
{
    [SQLite.AutoIncrement, SQLite.PrimaryKey]
    public int id { get; set; }
    public string TeamName { get; set; }
    public DateTime GameDate { get; set; }
}

下面是在表中创建的内容:

Table [TeamX]
Fields: 3
    [id]: integer
    [TeamName]: varchar
    [GameDate]: bigint
Foreign Keys: 0
Indexes: 0
Triggers: 0
Unique constraints: 0
Check constraints: 0
