"Could not load file or assembly System.Device.Gpio" on iot edge

Question

Tried to make a simple demo of using Gpio in C# on a Raspberry Pi with Azure Iot Edge. Included System.Device.Gpio" Version="0.1.0-prerelease.19171.3" in the project and it compiles perfectly and generates the docker module. But when the module starts on the Rasberry pi, I get an exception "System.IO.FileNotFoundException: Could not load file or assembly 'System.Device.Gpio, Version=0.1.0.0 ..."

Custom module in C# on Azure IOT Edge for Raspberry Pi (newest release using apt-get). Build with Visual Studio Code and Azure IoT Edge for Visual Studio Code. The module works fine when I am not using the Gpio library.

Module.csproj

…
<PackageReference Include="System.Device.Gpio" Version="0.1.0-prerelease.19171.3" />
…

Program.cs

…
using System.Device.Gpio;
…
using (var controller = new GpioController()){
  controller.OpenPin(17, PinMode.Output);
  controller.Write(17, PinValue.High)
}
