Network does not work when build target is WP8

I know TcpClient isn't supported in WP8 SDK, so i use the SocketClient from this tutorial http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh202858%28v=vs.105%29.aspx

During the build post processing, get the error:

This is no such TcpConnectAsync::SendCallback func calls in the class, what happens?

TIA!

 

1. Visit this page:

http://docs.unity3d.com/Documentation/Manual/wp8-faq.html

2. Read the explanation for what the message means. Follow the link to:

http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj207211(v=vs.105).aspx

3. Search on that page for System.Net.Sockets, and click the link to:

http://msdn.microsoft.com/en-us/library/windowsphone/develop/system.net.sockets(v=vs.105).aspx

This is the class for Sockets.

4. Follow the link to the Socket class:

http://msdn.microsoft.com/en-us/lib...elop/system.net.sockets.socket(v=vs.105).aspx

This page tells you what is supported on WP8 for the Socket class.

5. Now search for BeginConnect which is the API that fails for you. You won't find anything, which is the MSDN way of saying that this method is not provided on WP8. So then work out how to re-write your communication code.

 

There are no BeginConnect, EndConnect API calls in my class, I still dont the error's meaning.

Can you point out which func(s) fail the compiling?

 

there is a another network script in my project, after removing it, works now. Tank you!
