webform and office 365 API

Hi,

I am using visual studio 2013 to create web form to grab some mail from my office 365.

I did everything based on the instruction but when I run the app i get error:

For Each item As Array In JObject.Parse(content)("value")    -> JsonReader exception was unhandled by user code (Unexpected character encountered while parsing value: <. Path '', line 0, position 0."})

and when I try to show the response content on the webpage, it bring me up to log in page for my app. which means the log in was not successful.

What am I doing wrong?

Thanks for your help
