SurfPad: TCPIP Socket Connectivity

In the previous articles in this series, a UWP app was developed as an array of XAML buttons that acts as the UI for an app running on a remote embedded or IoT device. Once connected the remote app sends a configuration for the UI as a Json string. Connectivity between the UWP and remote apps over Bluetooth and USB Serial has been covered. In this article connectivity over network sockets is covered. The article includes 101 on TCPIP Network Sockets for UWP and Arduino.
