How do you manage environment-specific configurations for Azure apps?

Short answer: Use Azure App Service App Settings or Azure Key Vault. ASP.NET Core supports appsettings.json, appsettings.{Environment}.json, and environment variables. Example: // appsettings.Production.json { "ConnectionStrings": { "DefaultConnection": "Server=tcp:myserver.database.windows.net;Database=prodDB;..."

Example code

}
}
var connectionString = Configuration.GetConnectionString("DefaultConnection"); Q&A

Real-world example (ShopNest)

ShopNest on Azure typically uses App Service + SQL Database + Blob Storage + Application Insights for monitoring.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
