Wrox network programming book reincarnated
Back in late 2003 I suggested a friend pick up Professional .NET Network Programming from Wrox Press. He never did find it, as I think that was the time when Wrox started to go down the tubes, but as it turns out, he found that Apress got their hands on it.
Looks like it was reorganized a bit, but I'm sure it's still a good read, if for the chapters on the stream classes alone. Check it out.
