title: How can I use non-Silverlight assemblies in a Silverlight app?
body: <p>I'm working an project (pure hobby, "Sharping my skills") which has one unified back-end and multiple front-ends (ASP.NET MVC 1.0/JQuery and Silverlight 2). When I try to add reference to my business layer assembly in the Silverlight 2 project (VS2008); It gets rejected, because it's not a Silverlight assembly.</p>
  
  <p>Is their a way to include and reference a non-Silverlight assembly in a Silverlight app?</p>
