WCF + Silverlight + HttpContext.Current.Session is null

my problem....

i am tryingo to access session from Silverlight and WCF basicHttpBinding...

i saw some posts where it's possible (http://www.dotnetspider.com/Silverlight-Tutorial-317.aspx)

Mys cenario is:

Silvelright 4 FW 3.5

in web.config i have

<system.serviceModel>
    <behaviors>
        <serviceBehaviors>
            <behavior name="ViewModelDemo.Web.Service1Behavior">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="false" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <services>
        <service behaviorConfiguration="ViewModelDemo.Web.Service1Behavior" name="ViewModelDemo.Web.Service1">
            <endpoint address="" binding="basicHttpBinding" contract="ViewModelDemo.Web.Service1">
                <identity>
                    <dns value="localhost" />
                </identity>
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        </service>
    </services>
</system.serviceModel>

and my service:

[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class Service1
{
    [OperationContract]
    publicvoid Test()
    {
        var session = System.Web.HttpContext.Current.Session;
    }
}

and it''s call

                var client = new Service1Client();
                client.GetUserMacroFunctionsCompleted += new System.EventHandler<GetUserMacroFunctionsCompletedEventArgs>(client_GetUserMacroFunctionsCompleted);
                client.GetUserMacroFunctionsAsync();


void client_GetUserMacroFunctionsCompleted(object sender, GetUserMacroFunctionsCompletedEventArgs e)
    {
        var test =  ((Collection<Function>)e.Result);
    }

HttpContext.Current is always null!

Any suggestions?

This link probably to help you.

aspNetCompatibilityEnabled="true" doesn't help me till I set allowCookies="true" on the client binding configuration.

Update your web.config file to include

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />    
</system.serviceModel>

This should work, or else also change the AspNetCompatibilityRequirementsMode attribute on the contract to Required.

Yes HttpContext must be always null because your service configuration doesn't setup ASP.NET compatibility and your service doesn't require ASP.NET compatibility.

Add this to your configuration:

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

And change AspNetCompatibilityRequirements so that your service cannot be hosted without former configuration:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
