You will deploy 10 session hosts that will use MSIX app attach. Which directory service supports MSIX app attach?

MSIX app attach for Azure Virtual Desktop currently requires session hosts to be domain-joined to Active Directory Domain Services (AD DS). This is because MSIX app attach relies on specific Group Policy Objects (GPOs) and Kerberos authentication, which are native to AD DS environments. While Azure Virtual Desktop can integrate with Microsoft Entra ID (formerly Azure Active Directory) for user authentication, the underlying session host infrastructure for MSIX app attach specifically mandates AD DS for its operational requirements. Microsoft Entra Domain Services provides managed domain services but is not the sole requirement; AD DS is the fundamental directory service needed here.
