Entity Framework Core with UWP and Sqlite Revisited: Step by step

Entity Framework, in Code First Manner, can auto-generate the scaffolding for accessing a database from an app from an app’s model class. In a previous blog I covered some issues wrt using Entity Framework Core with a Universal Windows (Platform) app with a Sqlite backend database. The entities are specified as classes in in a .Net Core class project separate to the app project (within the same solution). The issue addressed in that blog was a problem referencing the class library from the UWP project. This blog revisits the same topic with an emphasis upon the steps required to implement an EF Core backed UWP app.

SurfPad: UWP Bluetooth to Bluetooth Connectivity Solved

The SurfPad project as on GitHub and hackster.io is a UWP app that runs on a touchscreen Windows device. It runs as the configurable UI for an app running on an embedded device such as an Arduiino device or a Raspberry Pi (running IoT Core).. The frontend sends single characters as commands (representing button presses) whereas the backend returns responses as text strings, representing sensor data that the remote device has determined. So the communication data is textual. The communication between the two devices can be a network sockets client-server conduit, USB Serial or Bluetooth Serial. Whilst Bluetooth Serial works OK between a Windows 10 desktop (or IoT Core) as the frontend and an Arduino device as the remote backend, using an IoT Core device as the backend has been shown to be problematic. This article presents an alternative based upon Bluetooth RFComm Chat client –server architecture, which does work.

Notes on RPI Windows 10 IoT-Core WiFi & BT Connectivity

Windows 10 IoTCore, as implemented on the Raspberry Pi 2 (RPI2)  initially came with no WiFi or Bluetooth (BT) connectivity. These were then added as USB dongles but with a limited listed of hardware that worked. RPI3 has built in WiFi and BT. What is the state of play with IoTCore connectivity with the RPI now? Are there any issues?
