You don't need to use back channel handler anymore. Install Microsoft.Owin.Security.Facebook -Version 4.0.0 (latest till date)

In Startup.Auth.cs,

app.UseFacebookAuthentication(
            appId: "xxxxxxxxxx",
            appSecret: "xxxxxxxxxxxxxxxxxxxxxxxxx"
        );

That's it, you don't need other infos, and delete BackChannelHandler class file
