Comment 1 Sebastien Pouliot 2013-03-05 16:37:53 UTC
The following code does not throw for me:

			System.Net.ServicePointManager.FindServicePoint ("http://img.msndev2.dev.ruwizards.com/tgk/3te/6m0/160/tgk3te6m01601p0tc8ii9luh9ps6li3k2i154j5p_srv1_medium.jpg", System.Net.WebRequest.DefaultWebProxy);

even with a diffferent URL (that returns a 404).

Can you give more details about the versions you use, if this happens on the simulator and/or device(s) (and which version of iOS runs on them) and if you have a proxy defined on the devices/sim.
Comment 2 Maxim 2013-03-06 00:48:45 UTC
I'm using:
	Mono 2.10.11 (mono-2-10/2baeee2)
	GTK 2.24.14
	GTK# (
	Package version: 210110000
Version: (Business Edition)

I'm test code above in iOS simulators 5.0 and 6.0.
Comment 3 Sebastien Pouliot 2013-06-02 11:53:04 UTC
If you can still reproduce this then we'll need a complete, self-contained, test case.
Comment 4 Maxim 2013-06-03 03:51:02 UTC
Yep. Since some MonoTouch update in my enviroment the problem disappeared.
Comment 5 Mohit Kheterpal 2014-03-26 08:56:52 UTC
As per comment 4, this issue does not exist.

Hence, closing this issue.
