Azure table storage using repository pattern and unit of work pattern - repository-pattern

Question

I'm trying to build a reusable code for accessing Azure Table Storage using repository pattern and unit of work pattern.
What I want to achieve is to instantiate an unit of work and then use that for different repositories.
Something like this:
MyUnitOfWork uow = new MyUnitOfWork();
uow.Users.Add(User user);
uow.Users.GetAllUsers();
uow.Users.FindUser(User user);
uow.Users.Delete(User user);
.......
uow.Products.Add(Product product);
uow.Products.Delete(Product product);
.......
uow.Invoices.Add(Invoice invoice);
.......
uow.Save();
I have some issues understanding how to implement this using TableServiceContext
Here is what I did so far ...
The model:
public class User : TableServiceEntity
{
public User(string partitionKey, string rowKey)
: base(partitionKey, rowKey)
{
}
public User()
: this(Guid.NewGuid().ToString(), String.Empty)
{
}
public string UserName { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
}
IRepository Interface:
public interface IRepository<T> where T : TableServiceEntity
{
IQueryable<T> Query { get; }
//bool CreateIfNotExist();
//bool DeleteIfExist();
//void AddEntity(T obj);
//void AddEntity(IEnumerable<T> objs);
//void AddOrUpdateEntity(T obj);
//void AddOrUpdateEntity(IEnumerable<T> objs);
//void DeleteEntity(T obj);
//void DeleteEntity(IEnumerable<T> objs);
}
Interface Unit Of Work:
public interface ITableUow
{
void Save();
IUserRepository Users { get; }
}
Interface User Repository:
public interface IUserRepository: IRepository<User>
{
IQueryable<User> GetUsers();
}
Azure Table Repository:
public class AzureTableRepository<T> : IRepository<T> where T : TableServiceEntity
{
public AzureTableRepository(TableServiceContext context)
{
if (context != null)
{
TableContext = context;
}
}
protected TableServiceContext TableContext { get; set; }
public IQueryable<T> Query
{
get { throw new NotImplementedException(); }
}
}
User Repository:
public class UserRepository : AzureTableRepository<User>, IUserRepository
{
public UserRepository(TableServiceContext context)
: base(context)
{
}
public IQueryable<User> GetUsers()
{
throw new NotImplementedException();
}
}
Azure Table Unit Of Work:
public class AzureTableUow: ITableUow
{
public void Save()
{
}
public IUserRepository Users
{
get { throw new NotImplementedException(); }
}
}
