WP7, How to use a service reference after adding it to Visual Studio 2010
When you added the service reference, you gave it a class name. Have a look in your solution explorer to see what you called it, and then you have to instantiate that class to use the service.
After you added a Reference using your WSDL URL:
Under Solution, under Service References, right click on your Service Reference folder that you want to reference (example: com.gold.services.description1)
Select View in Object Browser. You will see the class name in the Object Browser window that will open up. (example: GoldWeb.com.gold.services.description1)
Copy and paste the class name into your code.
Example:
using GoldWeb.com.gold.services.description1;
Then you are ready to start using its classes.
