Sup guys. I've been enjoying my new WP7 phone and totally digging exploring the OS internals!
Recently I've been getting into the "homebrew" app dev as I find it very educational and just plain fun! I wanted to release my contribution, which is full socket support. I have enough implemented to support client, tcp socket operations, but I'll probably implement the rest so one can host a socket (ie web server on the phone) or do ICMP. It's a lil rough around the edges, but still enough there that I wanted to share.
If you have a dev enabled device, just load up the 2010 project and deploy. This will not work on the emulator because I had to compile a native ARM COM dll (source included). I suppose this is also an ok example of how to compile and use native code on the device too.
Final note...Don't expect to get this by the market place...for fun only!
