Azure Functions Database Connection String

Question

How do I add or access an app.config file in Azure functions to add a database connection string?

If you\'re not supposed to add an app.config

Answer 1

The best way to do this is to add a Connection String from the Azure portal:

• From your Function App UI, click Function App Settings
• Settings / Application Settings
• Add connection strings

They will then be available using the same logic as if they were in a web.config, e.g.

var conn = System.Configuration.ConfigurationManager
                 .ConnectionStrings["MyConn"].ConnectionString;

Or if you're using a non-.NET language, you can use App Settings instead, which become simple environment variables at runtime that your functions can access.
