Currently, when IPv6 is disabled by the kernel, attempting to use the 'WebRequest' API with .NET native causes a crash. This can be recreated using the following gist: https://gist.github.com/redmcg/7d81ef833c77bee6965b5f441006f697
This patch fixes the crash by returning WSAEAFNOSUPPORT, as expected by .NET. See: https://referencesource.microsoft.com/#System/net/System/Net/Sockets/Socket.... ---
Changes since v1: - fixed compile error (sorry - I had tested against the wrong branch)
