Managing Configuration and App Settings for Multiple Environments in Your CD Pipeline

This post details how to manage configuration and app settings for multiple environments in a CD pipeline using Visual Studio Team Services. It explains two approaches: transforming web.config files before deployment using the 'Azure App Service Deploy' task with XML variable substitution, and applying settings directly to Azure websites using PowerShell cmdlets like 'Set-AzureRmWebApp' or a marketplace extension. It highlights the benefits of managing configuration through VSTS, including maintainability, reduced update locations, fewer mistakes, enhanced security, and increased reliability.
