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

If you are using function runtime v3, then following approach will work for you.

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true;",
    "AzureWebJobsDashboard": ""
  },
  "ConnectionStrings": {
    "MyConnectionString": "[YourConnectionStringHere]"
  }
}

In your function's startup file

public override void ConfigureAppConfiguration(IFunctionsConfigurationBuilder builder)
{
    var config = builder.ConfigurationBuilder.Build();
    var connectionString = config.GetConnectionString("MyConnectionString");
}
