c# - LiveSDK onedrive - How to read an album -

i trying follow sample on msdn read properties of folder on onedrive, running errors.

here tutorial following: http://msdn.microsoft.com/en-us/library/live/hh826522.aspx#reading_albums

the error when run code says:

"error 1 'testrun.mainpage' not contain definition 'session' , no extension method 'session' accepting first argument of type 'testrun.mainpage' found (are missing using directive or assembly reference?) c:\users\me\desktop\project"

am missing have run before click button? thing fails "this.session" parameter. barely learning livesdk i'm not sure if i'm missing reference or what. , :)

my code:

private async void button_login_click(object sender, routedeventargs e)         {             try             {                 liveconnectclient liveclient = new liveconnectclient(this.session);                 liveoperationresult operationresult =                     await liveclient.getasync("path/to/folder");                 dynamic result = operationresult.result;                 this.textblock_status.text = string.join(" ", "album name:", result.name, "id:", result.id);             }             catch (liveconnectexception exception)             {                 this.textblock_status.text = "error getting album info: " + exception.message;             }         } 

the session object stored in liveauthclient object when user logged in: http://msdn.microsoft.com/en-us/library/microsoft.live.liveauthclient.session.aspx

from error, looks session not method of current page, makes inaccessible method. you'll want store session object somewhere methods can access after user logs in.
