How to read,update and delete data in the silverlight4 project with "enabled wcf ria" using wcf ria.

Question

Hello, I m new in the silverlight and wcf ria. I have created a silverlight project with "enabled wcf ria". But when I read data using the following statement:

 LoadOperation<Users> loadOp = TBContext.Load(TBContext.GetUsersQuery());

 return loadOp.Entities.ToList<Users>();

I found that by debug loadOp.Entities' count is 0. I dont know why. If anyone can help me ?

If you know how to update/delete data, pls tell me, thanks in advance.

Answer 2

"loadOp.Entities' count is 0" because the sl communicate is asynchronous.

use the Entities.Add()/Remove() to operate the list .
