title: config web service from code behind
body: <p>I am creating a windows mobile 6 application which will consume a web service (.asmx) for different clients. 
  As I know, I will need to manually “Add Web Reference”; then I will be able to call those functions.
  Is it possible to configure web reference as a variable from code behind? 
  That way I can keep the url of web service in a text file. For different client, I just need to edit that text file instead of recompile that application again.     </p>
