I'm using DropBox.
What I did was:
1. subscribe to my app
2. test that it works
3. delete my app from the list of of granted apps in my user account (so I got the error I expected was something like "Unauthorized")
I tryed to debug. I found that a "System.Net.WebException" with a description containing a server error 401 is catched in
public static WebResponse GetResponse(WebRequest request) (source file "WebRequestStreamHelper.cs)
after that the error is thrown to... PerformWebRequest2 in (WebRequestService.cs)
that catch the WebException and returns null... so the real reason of the problem is lost. I see that the error is saved in a "out variable" but is there any way to retrieve it?
I'm trying to understand... but if you have the answer... please help me, thanks :-)
