Looks like PS Core 7 problem — it works fine on PS Core 6.2.3

@SteveL-MSFT @daxian-dbw we should investigate this

[SteveL-MSFT]

Setup a new 18362 VM, added RSAT AD mgmt feature, and installed PS7 preview.6 and Get-AdUser worked for me.

@jackfalveyiv @george-chakhidze are you still seeing this in PS 7-rc.1?

I have done extensive testing with the AD modules.

The AD DS Deployment module (used to add DCs etc) does NOT work natively but is fine via WInCompat. I have installed a Forest root DC, a second DC, a Child domain DC, a second forest root dc and connected with the first by a x-forest trust. The Active Directory module DOES works natively.

Aside from the warning message when loading the AD DS module, my Windows PowerShell code works fine for AD management.

@rjmholt Works fine in 7.0.0-rc.2 (I don't have rc.1 installed).

@doctordns time for a blog post on this? :)

[doctordns]

That could be done...

I have noticed this same thing with every version since 7.0 was released, but it is not consistent. Often it will work fine on a freshly opened PS window but if I come back the next day to the same window, AD commands no longer work again. Closing the window and opening a new one will make it work.

Currently running 7.1.0

Sorry for the necro, but just stumbled on this. Powershell 7.1.5, getting this error somewhat randomly. Different shell instances get this error with different cmdlets. Get-AdDomain sometimes, Get-AdForest sometimes.

PS C:\Users\anders.OZWCORP> Get-ADForest Get-ADForest: Type 'generatedProxy_4' from assembly 'ProxyBuilder, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is attempting to implement an inaccessible interface.
