Send using specific network interface

[maxstricker]

How can I select which network interface to use if my device has more than one?
For binding a listener I could use CommsInterface, but what if I want to send a UDP packet on a specific network interface? Lets suppose I have a wireless and a wired ethernet connection on my UWP tablet, and I want to send the packet using the ethernet connection. Both are in the same subnet and I have to control which one to use. The receiving App accepts the message only if coming from a specific IP.
