This call throws a PlatformNotSupportedException when running a Windows app, which references a library built for WindowsStore support, on a Windows platform. The same call succeeds on all other platforms, Android, iOS, and OS X. I started the PCL using the Xamarin template from James Montemagno's Visual Studio extension. Upon peeking at the reference it appears to be referencing
Assembly location: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\Xamarin.iOS\v1.0\System.dll
In a pure Windows application, the same call seems to be referencing this, and it works.
Assembly location: C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.dll
Is this a limitation, or am I doing something wrong? Either way, what do I need to do to get the proxy settings on Windows?
