Platform not supported exception if using PowerShell Import-Module

I have a C# DLL that has the System.Device.Gpio Version="1.0.0" and I want to use it with PowerShell, through Import-Module. Upon importing the DLL, if I try to create an I2cConnectSettings object, I get an exception saying that Operation is not supported on this platform. On the same project, I’ve created the Main method that does exactly the same. If I run dotnet donetIot_test.dll the code runs successfully.

I can’t seem to find the root cause of the exception, but the platform is the same (raspberry pi 3b) - assuming that the platform is the hardware.

If I run the dotnet donetIot_test.dll command inside PowerShell it works, so it doesn’t seem to be shell-related.

Here’s a link to the repo with a sample

Yes! That was exactly the problem! Since I saw the runtimes inside the publish folder, I didn’t even try to compile with the Linux as runtime.

Closing as the issue seems to be resolved.
