Hi Silverlight applications can only use assemblies compiled by Silverlight projects. There are exceptions but for anything UI related it's always true. As a result if you want to use a third-party library in your Silverlight application it needs to have a special Silverlight version to use instead of the normal version. The normal version is sometimes called the .NET4 version or the WPF version to contrast it with the Silverlight version. so my suggestion is to create one silverlight library project & use dll of this project.
