Build2020WvdMigrationDemo

Code for the demos shown in the Microsoft Build 2020 Skilling Session 127.

There are two solutions in this repo under the src directory:

1. The WvdMigration directory holds the WvdMigration WPF project used in the demo, along with the MsixPackage project. Neither of them has anything particularly novel.
2. The StageAppxPackage directory holds the StageAppxPackage tool which is an incredibly simply wrapper around PackageManager.StagePackageAsync -- ideally there will be a built-in PowerShell cmdlet soon that pairs with Add-AppxPackage.

The most interesting part of the repo is azure-pipelines.yml which was developed primarily by @Huios. It contains the commands to build the WPF app, package it as an MSIX, sign it correctly, create a VHD file, and expand the MSIX package into the VHD ready for MSIX AppAttach.
