SDK Usage

Introduction

The IoT Device C# SDK provides abundant demo code for devices to communicate with the platform and implement advanced services such as device, gateway, and OTA services. For details about the integration guide, see IoT Device C# SDK.

Requirements

.NET SDK 8.0 has been installed.
- .NET installation guide
- .NET 8.0.

The corresponding IDE (Visual Studio Code 2017+, Rider 17.0.6+) has been installed. This SDK does not depend on the IDE. You can select the IDE or directly use the CLI as required.

For details, see README.
