Custom cmdlet giving me a missing assembly error

Powershell gives me this error when I try run my cmdlet:

Get-UserFromId: Could not load file or assembly 'System.Net.Http.Formatting, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

Get-UserFromId: Could not load file or assembly 'System.Net.Http.Formatting, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

I'm using this guide to make API calls through this tutorial: https://stackoverflow.com/questions/9620278/how-do-i-make-calls-to-a-rest-api-using-c which told me to add that assembly. When I compile it and use ipmo to add it to my powershell, I get that error when trying to run it. I was required to reference System.Net.Http.Formatting to get ReadAsAsync<>() to work (I think). Am I just building my project wrong?

Okay thanks. I saw some other microsoft docs that looked similar enough to the stackoverflow post which is why I just settled for it. Ill go see what that top link is about

@oCeBeT I've used this doc to remake it. https://learn.microsoft.com/en-us/dotnet/fundamentals/networking/http/httpclient Still the same error:

Import-Module: Could not load file or assembly 'System.Management.Automation, Version=7.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

Im using this to code my cmdlet https://learn.microsoft.com/en-us/powershell/scripting/developer/cmdlet/how-to-write-a-simple-cmdlet?view=powershell-7.4 System.Management.Automation is what it says to import to write a cmdlet. Im running powershell 7.4 for macos. As for template… I just used a class library and continued from there.

i honnestly never tried to create a custom PWSH Module, but what i can tell is that super old "windows powsrshell" is powershell.exe ... BUT IS NOT "powershell / powershell core" which is pwsh and pwsh is cross platform and runs on netcore 6+ I'm suspicious on the base template you're using here's the one you're supposed to use: https://learn.microsoft.com/en-us/powershell/scripting/dev-cross-plat/writing-portable-modules?view=powershell-7.4&viewFallbackFrom=powershell-7

for a search For sure lol I generated the template but I think it generated a template that uses an old version of C#: csproj file:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <AssemblyName>Project</AssemblyName>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="PowerShellStandard.Library" Version="5.1.0-preview-06">
      <PrivateAssets>All</PrivateAssets>
    </PackageReference>
  </ItemGroup>

</Project>

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <AssemblyName>Project</AssemblyName>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="PowerShellStandard.Library" Version="5.1.0-preview-06">
      <PrivateAssets>All</PrivateAssets>
    </PackageReference>
  </ItemGroup>

</Project>

Is there a way to migrate it to a newer version?
