Disclaimer: this is a short description of a code snippet primarily for myself because I had failed to find corresponding details in MSDN as well as on Google about SocketOptionName.MulticastInterface parameter values. Feel free to use it if you're experiencing the same lack of luck. Multicasts... You have to learn them right after generic sockets (aka unicasts) and massive spam-like broascasts. According to their nature, multicasts gather one-shot-to-many strength of broadcasting and can pass boundaries of nested networks like unicasts. The only weak side is knowledge "how to tune the socket".

One of most remarkable events at 2012 was Windows roll-out: desktop Windows 8, tablet Windows RT and mobile Windows Phone 8 (here and after, WP8). Personally I'm a bit of Windows Phone evangelist and Windows Phone 8 launch, even delayed for few months, was a big interest for me, so I was eager to try it.
After WP8 SDK installation attempt, I learned that my Windows 7 workplace is obsolete. Almost no surprise here: if you need Win7 instead of old good WinXP to do WP7 development, why don't you need to upgrade your PC to Win8 before starting with WP8? Anyway, it was no reason (and no time, as usual) to re-settle my working environment from Win7 to Win8 just to try the new technology. The answer was stright-forward: let use virtual machine! So, the toolchain was obvious from the first glance: Win7 as a host, Win8 as a guest on virtual machine, then WP8 emulator to try the new SDK. After a long-enough time installing all the staff, the toolchain just failed on very last step. WP8 emulator been failed to launch, accompanied with incomprehensible error messages (very famous Microsoft-style, you can say).
Finally, if you're looking just for working solution, I can redirect you to one of proven ways to fix the problem: http://stackoverflow.com/questions/13148828/unable-to-create-the-virtual-machine. But if you're interested to take a deeper look, welcome to this note...
