webclient and expect100continue

Question

What is the best way to set expect100continue when using WebClient(C#.NET). I have this code below, I still see 100 continue in the header. Stupid apache still complains with 50

Answer 1

One of my below approach also worked,

In my constructor of class (service calling), you can set System.Net.ServicePointManager.Expect100Continue = false;

and then I have created BasicHttpBinding object and continued, it executed successfully.
