This article is about a little understood feature for MSIX packages that Microsoft added. Due to poor documentation, when originally released we deemed it unworkable. Recent discoveries in how to overcome the AppXManifest issues in how to implement have lead us to re-investigate this feature. We find, that while of limited practical use, there are application packages that need the feature to be successfully delivered at MSIX packages.
Last month we held a webinar on Flexible Virtualization (See Video) and released a White Paper (See White Paper) on it as well. Flexible Virtualization consists of two available features, FileSystemWriteVirtualization and RegistryWriteVirtualization. While we mentioned RegistryWriteVirtualization at that time, we did not focus on it as more research was still required. Now we are ready.
You can find part 2 of Flexible Virtualization in the white paper:
