Powershell Azure Function on Linux can't find types

Question

running linux powershell azure function with classes and it will not find types.

here's an example func script from the template with me adding a couple fields on a class

these fields show up as unknown types on my local dev environment and in the portal on azure

# POST method: $req
using namespace Microsoft.Azure.Commands.Profile.Models.Core
using namespace Microsoft.Azure.Commands.Common.Authentication.Abstractions

class Test{
    hidden [PSAzureContext] $azureContext
    hidden [IStorageContext] $storageContext

    Test([PSAzureContext] $ctx, [IStorageContext] $storectx){
        $this.azureContext = $ctx
        $this.storageContext = $storectx
    }
}

$requestBody = Get-Content $req -Raw | ConvertFrom-Json
$name = $requestBody.name

# GET method: each querystring parameter is its own variable
if ($req_query_name) 
{
    $name = $req_query_name 
}

Out-File -Encoding Ascii -FilePath $res -inputObject "Hello $name"

If those namespaces come from a PowerShell module, try `Import-Module` at the top of your code so it loads the needed assemblies — Santiago Squarzon, Jun 21 '23 at 22:17
Try to import the module at the top of the code, if that didnt help then the answer is in this question https://stackoverflow.com/questions/42837447/powershell-unable-to-find-type-when-using-ps-5-classes and we can close this as duplicate — Santiago Squarzon, Jun 21 '23 at 22:34
You need a "using assembly". See : https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_using?view=powershell-7.3 — jdweng, Jun 22 '23 at 08:25
@jdweng do you know which assembly and where? especially on the Azure box that this is going to run? — Chris Hayes, Jun 22 '23 at 16:28
@jdweng I'm sorry but that doesn't make sense, these are Azure cmdlet dlls — Chris Hayes, Jun 22 '23 at 16:51
I just removed the type info from the code for these variable/methods — Chris Hayes, Jun 22 '23 at 17:48

You can make use of below code in your Powershell run file, For IStorageContext to work, You can refer this answer by Reza Aghaei

My run.ps in Azure Function Http Trigger Powershell:-

using namespace System.Net

# Input bindings are passed in via param block.
param($Request, $TriggerMetadata)

Import-Module Az.Resources
Import-Module Az.Accounts



$AppId="xxxxxb838-6d26a31435cb"
$AppSecret="xxxxxZ3ZgxRt8313-CS0ifbLE"

$SecureSecret = $AppSecret | ConvertTo-SecureString -AsPlainText -Force

$Credential = New-Object -TypeName System.Management.Automation.PSCredential `
-ArgumentList $AppId,$SecureSecret

$TenantID="xxxx4ce4-99ed-af9038592395"

Connect-AzAccount -ServicePrincipal -Credential $Credential -Tenant $TenantID 

$AccountName = "siliconrgaaa6"
$ResourceGroupName="siliconrg"

$StorageAccount=Get-AzStorageAccount -Name $AccountName  -ResourceGroupName $ResourceGroupName
# $storageAccountBlob=Get-AzStorageBlob -Container "blob" -Context $storageContext  -Prefix "host"

Function SomeCmdlet {
  param(
    [parameter(Mandatory=$true)]
    [object]$storageContext
  )
  New-AzureStorageContainer -Name "blob" -Context $storageContext -Permission Off
}

$StorageAccount
$ResponseMessage="The kind of storage account is " + $StorageAccount.kind

Push-OutputBinding -Name response -Value ([HttpResponseContext]@{
    StatusCode = [System.Net.HttpStatusCode]::OK
    Body = $ResponseMessage })

Make sure you uncomment Az module in requirements.psd like below:-
