Microsoft.Graph and PnP.PowerShell conflict (Could not load type 'Microsoft.Graph.Authentication.AzureIdentityAccessTokenProvider')

[kpinel]

Describe the bug When loading the latest versions of PnP.PowerShell and Graph and running any Graph query, we get the following error Could not load type 'Microsoft.Graph.Authentication.AzureIdentityAccessTokenProvider' from assembly 'Microsoft.Graph.Core

To Reproduce Steps to reproduce the behavior:

1. Import-module pnp.PowerShell
2. Connect-mggraph
3. Note error Connect-MgGraph: InteractiveBrowserCredential authentication failed: Could not load type 'Microsoft.Identity.Client.BaseAbstractApplicationBuilder'1' from assembly 'Microsoft.Identity.Client, Version=4.50.0.0, Culture=neutral, PublicKeyToken

Load graph first

1. Connect-MgGraph
2. Connect

Expected behavior Expect both modules to be able to work together

Additional context Also reporting the same bug in PnP.PowerShell just in case

Workaround
Connect-MgGraph Perform graph command Connect-PnPOnline

Commands from both modules seem to work after this

Hi @kpinel thank you for identifying and logging this issue and also providing a work around. The reason you are having that error is because of a conflict in the Microsoft.Graph.Core assemblies loaded in your session. pnp.PowerShell is using an old version (1.25.1.0) while Microsoft.Graph.PowerShell is using a newer version (3.0.9). I would suggest that you log this issue here https://github.com/pnp/powershell/issues, requesting that team to update their Microsoft.Graph.Core version.

As noted in my original post, I had also posted into pnp PowerShell. Closing this one and putting pressure on the PnP team

FYI, to resolve this I just deleted the Microsoft.Grap.Core.dll in the PNP module folder. All works now.

I am using modules: PnP.PowerShell 2.5.0 Microsoft.Graph 2.21.1

I have had similar issues in the past where one module was updated and the others weren't.
