I have a UWP app I created and want to use powershell to create a shortcut on the desktop.
Creating a shortcut is easy for an exe
$TargetFile = \"\\
Creating shortcut for UWP app is a different story from classic desktop. You can refer to my another answer Where linked UWP tile?
To create a shortcut of an UWP app on the desktop using powershell, you can for example code like this:
$TargetFile = "C:\Windows\explorer.exe"
$ShortcutFile = "$env:USERPROFILE\Desktop\MyShortcut.lnk"
$WScriptShell = New-Object -ComObject WScript.Shell
$Shortcut = $WScriptShell.CreateShortcut($ShortcutFile)
$Shortcut.Arguments="shell:AppsFolder\Microsoft.SDKSamples.AdventureWorks.CS_8wekyb3d8bbwe!App"
$Shortcut.TargetPath = $TargetFile
$Shortcut.Save()
You can find the AppUserModelId using the method in the link provided by @TessellatingHeckler, and replace the Microsoft.SDKSamples.AdventureWorks.CS_8wekyb3d8bbwe!App
in the code with your desired AppUserModelId.
