Uninstall all dependant apps in Business Central On-premise

Uninstall all dependent apps

Ever tried to uninstall a Business Central app in PowerShell, and failed due to dependencies on that app? I hit that problem and decided to share a script to detect and uninstall all dependant apps.

I was looking to publish an app from VS Code on a copy of a customers database so I could debug and develop locally and needed to uninstall the app first before I could deploy. The problem was, this app was a dependency for several other apps created for the customer.

What I found is we can get a full list of apps installed with the Get-NavAppInfo cmdlet, then for each app iterate through the dependencies until we find our app:

The script prints out a list of app names and versions which can be used for reinstalling them after. 

Hope this is useful for someone else.
