title: Consuming web services in C#
body: <p>I just started playing around with some API's in C#.  In my form I had added a service reference <a href="http://wsf.cdyne.com/WeatherWS/Weather.asmx" rel="nofollow">http://wsf.cdyne.com/WeatherWS/Weather.asmx</a>.  Everything works great and I am able to utilize its library.  Now I am trying to use for example <a href="http://free.worldweatheronline.com/feed/apiusage.ashx?key=(key" rel="nofollow">http://free.worldweatheronline.com/feed/apiusage.ashx?key=(key</a> goes in here)&amp;format=xml. [I have a key] Now when I try to use it as service reference I am not able to use.  </p>
  
  <p>Do I have to call it in my form instead of referencing it? or do some sort of conversion?  Also does it matter if its xml or json type?</p>
