Cross-Platform IoT Programming with .NET Core 3.0

摘要

Microsoft Build 2019 brought exciting news for .NET developers: .NET Core 3.0 now supports C# 8.0, Windows Desktop and IoT, so you can use your existing .NET skills to develop cross-platform apps for smart devices. In this article I'll show you how to create a .NET Core app for Raspberry Pi 2/3 with the Sense HAT add-on board. The app will obtain various sensor readings, and the most recent readings will be accessible through the ASP.NET Core Web API service. I'll create the simple UI for this service with Swagger (Figure 1), which will let you easily interact with the IoT device. Besides getting data from the device, you'll also be able to remotely change the color of the Sense HAT's LED array (Figure 2). The companion code is available through my GitHub page: bit.ly/2WCjOG2.
