Loading .NetCore DLL's in powershell

Question

I've created some .DLL's compiled using .NetCore 1.1. I now need to load them into Powershell and call their methods. Is this supported or do my DLL's need to be compiled using the full version of .Net?

Answer 1

Your .NET Core dlls won't run on standard out of the box windows only flavored powershell.

But! There is a .NET Core friendly version of powershell here: Powershell Core.

Powershell Core will run on Windows, Linux, and macOS, just as .NET Core was meant to run.

Answer 2

I came across this question when trying to do something similar. I succeeded in loading a .NET Core dll in the following way:

// You can use namespaces, but also paths
using assembly 'C:\Program Files\dotnet\shared\Microsoft.NETCore.App\3.1.4\System.Text.Json.dll'

// Specific for the static method I use in my example
$options = New-Object System.Text.Json.JsonSerializerOptions

// Use the Serialize method of the static class JsonSerializer
$jsonString = [System.Text.Json.JsonSerializer]::Serialize($device, $options);

I used System.Text.Json, but you can do this with any dll.
