Silverlight TV 70: Ever wonder how to use sockets or what they're good for? In this week’s episode of SLTV, Peter Smith of the Silverlight networking team joins John to discuss these topics and demonstrate how sockets work by using them to play an "I Spy"-like game that Peter created. The game results and scores are updated instantly on two client PCs, and after Peter and John play, Peter jumps into the code and shows how the socket service works on both the client and the server.
