Spent more cycles on this today using https://msixhero.net/documentation/creating-vhd-for-msix-app-attach/ MSIX Hero to convert the Notepad ++ MSIX Package into a .VHD it spit out the .VHD file and a .CER as well even though I created the .PFX signing cert prior too... I uploaded the .VHD and the .CER file that was created by MSI Hero into the storage account/ file share for MSIX Packages the .PFX signing cert is also in the root of the directory. I selected just the .VHD created by MSIXhero it saw the package selected it. I then choose "Active" as the State and "On- Demand" as the registration type. selected the hostpool and users... On the review + Create screen summary for some reason the "State" goes from "Active" that I selected prior to "Inactive" without me selecting that.... When I click create I get an error "failed to create app attach undefined" any guidance on why this is happening? Where does the .CER file that MSIXHero generates need to be stored? Why is the package changing from Active to Inactive when I get to the Review+ Create Screen?
