Asp.Net Boilerplate, How to apply queries on database tables?

Question

I am using Asp.Net boilerplate framework, I created a table in database by Code-First approach. Now i want to get Records from that table but applying query like this returning empty data. Why?

 MyAppDbContext db = new MyAppDbContext();
 var list = db.NewTables.ToList();

But List is returned as empty while table contains data actually.

Inject IRepository instead of using DbContext directly:

public class TaskManager : DomainService, ITaskManager
{
    private readonly IRepository<Task, long> _taskRepository;

    public TaskManager(IRepository<Task, long> taskRepository)
    {
        _taskRepository = taskRepository;
    }

    public void GetTasks()
    {
        var tasks = _taskRepository.GetAll().ToList();
    }
}
