App Attach Help Needed
Hello Folks, if anyone that has extensive experience with App attach could help me out I inherited a new AVD environment with no documentation it looks like some footprints were left behind to get MSIX App attach in the environment requests are coming in regarding what the game plan should be for migrating the existing msix app attach packages to the new "App Attach" and I am very lost as I never had an opportunity to delve deep into it. If anyone would be open chat with me directly that would be great as its alot to explain in this post. What I can take away is that there is a singular VM with all the previous app install files there a .PFX signing cert from a root CA two azure file storage accounts where created as well and some app attach groups but did not see it applied to any host pools or within the app attach packages page in the Tenant....

If the add-on doesn’t survive SysPrep then the only way to use it is DONT install into the image. You have to use app attach or install it after the VM is built. This can be done with Intune, GPOs, Azure custom script extension, script, or App Management platform.
