title: Dynamic service reference in Silverlight
body: <p>I'm building a Silverlight application that interfaces with SharePoint Web Services.  In a windows forms application I'd create a web reference to my local SharePoint server, then change the Uri of the reference at runtime to point to whatever SharePoint site I wanted to use.  Silverlight doesn't seem to have web references, but similar functionality can be achieved with service references. However, there doesn't seem to be a way to change the Uri of the reference at runtime.  Is there a way to do this in Silverlight?  Or a better way of using  SharePoint web Services from Silverlight?</p>
  
  <p>Note:  I need to access list item attachments, so owssvr.dll won't be sufficient (I think?)</p>
