If like me you may have been accustomed to drag/drop a DLL into the GAC and finding doesn’t work in Windows Server 2012? There are a number of solutions but sharing a Powershell script I have found useful for this purpose.
From SharePoint Powershell console:
[System.Reflection.Assembly]::Load(“System.EnterpriseServices, Version=220.127.116.11, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a”)
$publish = New-Object System.EnterpriseServices.Internal.Publish
