Any news on RC2 chris?

Hi David and welcome to the forums!

I think you'll find your answer here:

We just downloaded the final SDK and PK. We'll build an "RC3" build based on this and post it by early next week.

~~Ugh. I'd only tested UDP and TCP listen. I had not tested a TCP socket.Connect then socket.Send. I can't get it to work either, but only for TCP and Sending... UDP seems to work fine.~~

Update: It turns out I do have code that does this in one of my apps. And it works fine. I think it doesn't work until after the IP address is obtained by Netduino. I don't really know what to look for to see if the network connection is ready. Here is the actual working code from my app:

using (var s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) { SendTimeout = 2000 })
{
     var entry = Dns.GetHostEntry(host);  // DNS lookup
     var address = entry.AddressList[0];
     var ep = new IPEndPoint(address, 80);

     s.Connect(ep);

     s.Send(Encoding.UTF8.GetBytes(message));

     s.Receive(response);      
}

There were some networking bugs introduced with RC2/RC3. I just saw a bugfix posted on netmf.codeplex.com. We'll get it checked in within this next week and issue a new RC4 firmware build. Chris
