Some notes on adding and removing migrations in Entity Framework core.
EF Code First approach (Create class/es first)

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.
Issue: Can pair a Windows 10 device with an Arduino device and communicate over RFCOMM. But although can pair two Windows 10 devices over Bluetooth Serial, I can’t serially transmit between them: No serial port for OutGoing end.
This article covers using a Raspberry Pi running a RS4 version of IoT Core as the SurfPad, withe an Arduino devices as the Remote app. Connectivity for this is via Bluetooth..
As part of a series of articles on a set of projects targeted at using a Windows Surface device as the presentation layer for a RPI or Arduino device, this article views the apps as state machines and documents the app states coupling through message passing between them.
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.
This article reworks the previous few articles that use BT Serial and the connectivity so that USB virtual serial is used for communication. It covers in detail USB Serial connectivity between a UWP app and an Arduino devices as well as with a Windows 10 IoT-Core device (eg RPI).
Turn your old Surface into into a large touchpad. As part 2, specify the buttons and app config via a Json Configuration file. This reworks a previous GitHub project.

Have you got an old RT Surface 1 or 2 gathering dust and don't know what to do with it?
We are looking a short-cutting getting started with Xamarin Forms for cross platform app development, if you are already a UWP app developer. This article discusses the rudiments of an Xamarin Forms app project from the perspective of a UWP app developer.
