Hi All!

Compiling and running DotNetExample on Windows is fine. But when i try to do the same with XamarinExample on Mac, I`m getting linking error:

Further investigations show that Photon3DotNet.dll containts methods in SocketUdpNativeDynamic class:
[DllImport("PhotonSocketPlugin")]
    private static extern IntPtr egconnect([MarshalAs(UnmanagedType.LPStr)] string address);
    [DllImport("PhotonSocketPlugin")]
    private static extern void egdisconnect(IntPtr pConnectionHandler);
    [DllImport("PhotonSocketPlugin")]
    private static extern byte eggetState(IntPtr pConnectionHandler);
    [DllImport("PhotonSocketPlugin")]
    private static extern int egread(IntPtr pConnectionHandler, byte[] arr, int size);
    [DllImport("PhotonSocketPlugin")]
    private static extern void egsend(IntPtr pConnectionHandler, byte[] arr, int size);
    [DllImport("PhotonSocketPlugin")]
    private static extern int egservice(IntPtr pConnectionHandler);

It seems I need PhotonSocketPlugin library, but i can`t find it anywhere.
Any suggestions?

If it could help I attach soft I use:

    Ow. That problem is known but so far only for Unity.
    The problem is that we first had to include 2 classes which import native libraries when we need them but that code breaks compilation even if we don't use it when the native libs are not available.

    I think I can provide you with a new lib on Monday.
    Sorry for the issues and the delay.

    Thank you for your reply, Tobias.

    Looking forward for a new lib. :)

    Aleksei: Please download the updated assembly from:
    https://dl.dropboxusercontent.com/u/4295285/Photon3DotNet-NoNativeSockets_v4-0-0-0.zip

    Disclaimer: This is the current version we have and I didn't explicitly test it on Xamarin iOS export. I just made sure it doesn't try to import the native libs which are only available for Unity builds.
    This is meant as quick fix but should work by all means.

    I am not around for a week but we should be able to update the SDKs properly in the next weeks.

    I`ve tried new lib. Sample compiles and runs just fine.

    Thank you for quick response, Tobias. :)
