Thread started by asked for a C# port of a C socket server for Windows Phone 7. As noted, the C# forum often has deeper examples; 's comment about not rewriting the server is relevant — porting the client is usually faster and safer than reimplementing a production server.

Important platform and protocol notes: Windows Phone socket support requires the OS/SDK that exposes System.Net.Sockets (Windows Phone OS 7.1/Mango and later). Socket operations must be asynchronous on the phone UI thread. Confirm whether the C server uses TCP or UDP, any binary struct layouts, message framing (length-prefix vs delimiter), and endianness. C struct padding and compiler-dependent packing will not map automatically to C#; serializing fields explicitly (byte arrays, BitConverter, IPAddress.NetworkToHostOrder) is the reliable approach. If the server uses raw IP headers or privileged operations, the phone platform will not support that.

Minimal pattern (Begin/End async) for a TCP client on WP7:

using System.Net;
using System.Net.Sockets;
using System.Text;

var sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
sock.BeginConnect(new IPEndPoint(IPAddress.Parse("192.168.1.100"), 12345), ar =>
{
    try
    {
        sock.EndConnect(ar);
        var buf = new byte[1024];
        sock.BeginReceive(buf, 0, buf.Length, SocketFlags.None, iar =>
        {
            int r = sock.EndReceive(iar);
            // process buf[0..r]
        }, null);
    }
    catch { /* handle errors */ }
}, null);

Quick testing tips: run a simple TCP server on a PC, open the firewall port, and use the PC LAN IP when using the WP7 emulator (127.0.0.1 on the emulator will not reach the host). Log raw bytes (hex) and verify handshakes with Wireshark or netcat to match the C server protocol exactly.

LOL! Why would someone go out of their way to re-write a server for a random person with 4 posts? I mean, would you do this for someone? I sure hope not...
