proposed querying pattern

gistfile1.java

// setup a specification
var specification = new UserWithClientSpecification(userId);
var userWithClient = userService.RetrieveWithSpecification(specification);


// and the specification class would be...

public class UserWithClientSpecification : ISpecification<User>
{
  public UserWithClientSpecification(int userId) 
  {
    this.userId = userId;
  }

  public IList<User> Filter(IQueryable<User> users)
  {
    return users.Where(u => u.UserId == userId);
  }

  public string EagerLoad()
  {
    return "Client";
  }

}
