This is a fork of OpenRGB.NET supporting .NET standard 2.0, so you can use it in your .NET framework projects.
You can also use the 1.x versions of the original OpenRGB.NET project, that supports .NET framework too.
OpenRGB.NET is a C# client for the OpenRGB SDK. It is meant to be a simple client, providing a method for each of the functionalities available in the SDK. Tested on Windows 10 and Arch Linux.
You can simply add the nuget package as a reference to your project.
