PowerShell utilities for migration/deployment tasks with Azure App Service
Add-AzWebAppFile - Uploads files to the App Service file system.
Set-AzWebAppSettings - Applies settings from a property file in key=value form to App Service.
Bonus utility
Not app-service specific but often useful in the same context
Remove-NonLatestSnapshots - When running a release pipeline in Azure Pipelines on a Maven snapshot artifact, multiple versions of the same file (typically a Jar file) may be present. In such cases, this command can be used to keep only the latest one.
