await async function C#

I am developing a Silverlight project using WCF.I need to call a function from WCF after another WCF function has finished.Here is my code : 

Int32 id = Convert.ToInt32(((TextBlock)dataGrid1.Columns[0].GetCellContent(dataGrid1.SelectedItem)).Text.ToString());
        Service1Client obj = new Service1Client();
        obj.DeletePersonAsync(id);

        //Wait for delete operation

        obj.GetPersonListCompleted += new EventHandler<GetPersonListCompletedEventArgs>(ListPeople);
        obj.GetPersonListAsync();

How can i do that?

Call the function "GetPersonListAsync" int the callback of obj.DeletePersonAsync(id) function. The code will be soemthing like as follows:

   private void somefunction()
{
    Int32 id = Convert.ToInt32(((TextBlock)dataGrid1.Columns[0].GetCellContent(dataGrid1.SelectedItem)).Text.ToString());
    Service1Client obj = new Service1Client();
    obj.DeletePersonAsyncCompleted += new EventHandler<DeletePersonCompletedEventArgs>(PersonDeleted);

    obj.DeletePersonAsync(id);
}


    private void PersonDeleted(DeletePersonCompletedEventArgs serviceResponse)
    {
     //Wait for delete operation

    obj.GetPersonListCompleted += new EventHandler<GetPersonListCompletedEventArgs>(ListPeople);
    obj.GetPersonListAsync();
    }
