As you have created an anonymous(Anonymous types are generated by the compiler, so we cannot know the type name in our codes) class so that you can not return it.Create a separate class with three properties Id,Name and Address then returned it.

  public class Contact
        {
            public int Id { get; set; }
            public string Name { get; set; }
            public string Address { get; set; }

        }

 private IList GetJoinAAndB()
    {
        var query = from a in objA
                    join b in objB
                    on a.ID equals b.AID
                    select new Contact{ a.ID, a.Name, b.Address };
        return query.ToList();
    }
