title: Production Configuration for Azure Function App
body: <p>In aspnetcore apps we include a appsettings.{environment}.json for each configuration / environment.</p>
  
  <p>Looking at deploying our first function apps - I have a testing and production stage set-up for our release pipeline.</p>
  
  <p>How do I go about setting the environment and corresponding configuration file to use for a function app?  Is it the same environment variable without the full IHostingEnvironment?</p>
