You have an Azure Virtual Desktop deployment. You need to recommend a solution to run containerized applications without installing the applications…

MSIX app attach is the recommended solution for delivering containerized applications in Azure Virtual Desktop (AVD) without installing them on session hosts. This technology uses MSIX packages to dynamically attach applications to a user session at logon. The applications run in a lightweight container, isolating them from the operating system. This approach simplifies session host image management, reduces image size, and allows for easier application updates and assignments to users without modifying the base virtual machine image.

A. EXE applications: These are traditional executable files that require direct installation on the session host's operating system, which contradicts the core requirement.

B. MSI packages: These are Windows Installer packages that also install applications directly onto the session host, rather than attaching them dynamically.

C. APPX app packages: These are primarily for Universal Windows Platform (UWP) apps and are installed on the operating system, not dynamically attached as required by the scenario.

1. Microsoft Learn. (2023). What is MSIX app attach?. In the "Key features" section

it states

"MSIX app attach is a way to deliver MSIX applications to both physical and virtual machines... When a user signs in

you dynamically attach the MSIX package with the application to their session. The application is contained in the MSIX package and is separated from the user and the operating system."

2. Microsoft Learn. (2024). Application management overview for Azure Virtual Desktop. This document explicitly contrasts MSIX app attach with traditional methods. Under the "MSIX app attach" section

it clarifies

"The applications aren't locally installed on session hosts

which makes it easier to create custom images for your session hosts and helps to reduce cost for your organization."
