Question

I am using Facebook C# SDK V6 and am using this tutorial.

http://csharpsdk.org/docs/web/getting-started

I have got nearly everything working – however every time I try to assign my Access Token to my context.Session[“AccessToken”] I receive a null exception.

Here is the bit of code:

public void ProcessRequest(HttpContext context)
    {
        var accessToken = context.Request["accessToken"];
        context.Session["AccessToken"] = accessToken;

        context.Response.Redirect("/Facebook.aspx");
    }

It errors on line 2 – during debug I can see the Session is null as it comes into the handler.

I am using webforms for this example.

Any help would be great.

Answer 1

The docs have now been updated with the fix.

public class FacebookLogin : IHttpHandler, System.Web.SessionState.IRequiresSessionState

inherit from IRequiresSessionState so you can access the session.
