Errors while compile in XamarinDataChannelTest sample project in release configuration

[SPNGUK]

Hi, I would like to use Sipsorcery in my Xamarin iOS app. When I try to compile the Xamarin sample project, I got some errors from VS on my Mac.

_/Users/SP/Downloads/sipsorcery-master/examples/WebRTCExamples/XamarinDataChannelTest/XamarinDataChannelTest.iOS/MTOUCH: Error MT5210: Native linking failed, undefined symbol: FormatMessageW. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in. (MT5210) (XamarinDataChannelTest.iOS)

Other errors are the same except referring different symbol: _RegCloseKey, _RegEnumKeyExW, _RegOpenKeyExW, _RegQueryInfoKeyW, _RegQueryValueExW.

The sample project works fine on an ipad simulator but I just can't compile to release.

Thank you.

I haven't seen any other devs using this library with Xamarin in the recent past so there may not be too much help available. It's a looong time since I played around with it.

Thanks for the quick response! Yeah, it's a legacy app.

Those missing symbols seem related to the Win32 API, but I couldn't find them in the sipsorcery code. Any chance they're being referenced somewhere?

I was able to build on Windows (after installing the now unsupported Xamarin component) and run the app in the Android emulator (didn't try iOS as I don't want to insall iTunes).

The Win32 calls to _Reg etc. aren't coming from the sipsorcery library so must be part of Xamarin.

Given the time since this example has been worked on and the fact that Xamarin is no longer being supported I don't think it's likely the approach in this example will be useful anymore. I'm going to remove it.
