Description Miha Markic 2013-10-22 12:37:56 UTC
I am using WebClient.UploadValuesTaskAsync method to get a text from a HTTPS based Uri. It returns "Error" string (bytes for string of course).
The non-async counterpart WebClient.UploadValues works fine and the async MS version on Windows works as well.

I guess the problem might be caused from the fact that I am using untrusted certificates with 
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
workaround.
