Direzione di ricerca

Begin with the dependency change associated with #3789 and the Microsoft.Graph.Authentication entry point used by Connect-MgGraph; reproduce on the listed PowerShell and .NET versions. Trace the System.Text.Json 10 load path and verify that the callback connects on 2.41.0 without pinning 2.40.0.

Descrizione

Describe the bug

We encountered an assembly-loading failure at Connect-MgGraph after installing Microsoft Graph PowerShell 2.41.0. Pinning both Microsoft.Graph.Authentication and Microsoft.Graph.Groups to 2.40.0 (the previous version) appears to resolve the failure.

Component Version
OS Ubuntu 24.04.4 LTS
PowerShell 7.5.5
PowerShell runtime .NET 9.0.14
Az.Accounts 5.3.3
Microsoft.Graph.Authentication 2.41.0
Microsoft.Graph.Groups 2.41.0

This runs on an ephemeral Azure DevOps agent. An AzurePowerShell@5 task (using pwsh=true) invokes Redgate Flyway, which launches a child pwsh process for a deployment callback. Diagnostics from the task and a seperate child process both reported the runtime and available module versions above.

Expected behavior

We would expect to be able to roll forward without issue.

How to reproduce

The callback imports the following modules and connects using an access token obtained through Az.Accounts:

Import-Module Az.Accounts -ErrorAction Stop
Import-Module Microsoft.Graph.Authentication -ErrorAction Stop
Import-Module Microsoft.Graph.Groups -ErrorAction Stop

$azContext = Get-AzContext -ErrorAction Stop
$graphAccessToken = (
  Get-AzAccessToken `
    -ResourceTypeName MSGraph `
    -TenantId $azContext.Tenant.Id `
    -AsSecureString
).Token

Connect-MgGraph -AccessToken $graphAccessToken -NoWelcome

This fails with an assembly-loading error referencing:

System.Text.Json, Version=10.0.0.0
SDK Version

2.41.0

Latest version known to work for scenario above?

2.40.0

Known Workarounds

Rolling back to 2.40.0 works as expected.

  • Installing the umbrella Microsoft.Graph module does NOT resolve the failure.
  • Installing the .NET 10 SDK on the agent did not resolve the failure, but we did not validate that the PowerShell callback ran under .NET 10 (it is believed we'd need to upgrade PowerShell 7 to do this)
