How to access ASP.NET session in Silverlight?

This explain how to access ASP.NET Session in Silverlight
To begin with Silverlight cannot access Session of ASP.NET as Silverlight is on client
side and ASP.NET is server side and there is no direct communications between
Now, the question is how to access ASP.NET session state from
Silverlight application. Here is an approach how to accomplish this, let us examine
the steps to achieve this:
1) Create a service contract which exposes
a session query method using WCF as we consume this from Silverlight as Silverlight
cannot directly talk to ASP.NET.
public interface ISessionService
string SpeakToASPNETSession(string str)
2) To implement this service contract, create a WCF service
class applying AspNetCompatibilityRequirementsAttribute.
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed]
public class WcfServiceToSession: ISessionService
public string SpeakToASPNETSession(string str)
return HttpContext.Current.Session[str] as string;
3) Finally, we need to enable the aspNetCompatibility function
in the Web.config by adding the following line:
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
