4.3Delivering apps on session hosts

Key points

Understand app deployment methods, application groups (desktop/RemoteApp) and user assignment, Microsoft 365 Apps and OneDrive (multi-session), and dynamic app delivery with App attach.

How you deliver apps is a choice of baking into the image, distributing individually, or mounting dynamically. In AVD, the publishing unit is the application group.

4.3.1Application groups and RemoteApp

There are two application group types: a desktop app group (publishes a full desktop) and a RemoteApp group (publishes individual apps as seamless windows). Assign users/groups to publish them, surfaced together to users via a workspace. Distinguish "deliver only specific apps, not a full desktop" = RemoteApp. Note design constraints on mixing desktop and RemoteApp publishing on a single host pool.

4.3.2M365 Apps, OneDrive, and App attach

Microsoft 365 Apps and OneDrive are deployed for multi-session by configuring shared computer activation and OneDrive multi-session settings. The current app-delivery method App attach (the evolution of MSIX app attach) packages apps onto storage and mounts them dynamically at logon. You can update/add apps without rebuilding the image, controlling delivery via user/group assignment. For "deliver apps dynamically without baking into the image and update easily," App attach is the norm (distinct from manual MSIX placement or recreating images each time).
