A common problem when developing Silverlight applications is how to share classes and in particular (Entity Framework) entities which are compiled for the full .NET framework in a Silverlight application. Silverlight is a browser plugin and a platform independent subset of the full .NET framework. Therefore Visual Studio does not allow referencing .NET assemblies from your Silverlight application.

Fortunately there is a very simple technique to share and reuse source code. Full details of which you can find in the link below

In this article Stefan Cruysberghs demonstrated this technique with several real world examples and I will give you some handy tips.

• Referencing assemblies
• Linking files in Silverlight assemblies
• Using the SILVERLIGHT compiler directive
• Sharing code between WPF and Silverlight
• Sharing (POCO) entities between your .NET domain layer and Silverlight
• Sharing extension methods between .NET and Silverlight
• Sharing logic in your Entity Framework entities between your .NET domain layer and Silverlight
• Sharing common logic and separating framework dependent implementations

This linked has helped me, as I have SOA, where WCF Services, DataContracts, ServiceContracts are shared between my ASP.NET , WPF and Silverlight application.
