 The Terminal is bundled as an `.msix`, which is produced by the `CascadiaPackage.wapproj` project. To build that project from the commandline, you can run the following (from a window you've already run `tools\razzle.cmd` in):
 
 ```cmd

 This takes quite some time, and only generates an `msix`. It does not install the msix. To deploy the package:
