The bundle manifest file is an XML document that contains a list of app packages and resource packages in the bundle.
The bundle manifest contains info about the architectures and resources of each package. When you install the bundle on a computer, you can use this info to determine the subset of packages that apply to that computer.
Visual Studio and the MakeAppx packaging utility automatically create and insert a bundle manifest schema (BundleManifest.xml) when they build each ZIP bundle.
