title: Sharing / transforming appsettings across projects and environments
body: <p>I got a Visual Studio solutions with multiple projects (function apps and a web API) and a datalayer that is shared between all the projects. I've set up the solution so all projects share the same config (<code>appsettings.json</code>) based on this article: <a href="https://andrewlock.net/sharing-appsettings-json-configuration-files-between-projects-in-asp-net-core/" rel="nofollow noreferrer">https://andrewlock.net/sharing-appsettings-json-configuration-files-between-projects-in-asp-net-core/</a> </p>
  
  <p>All projects are based on .net core. </p>
  
  <p>I've set up a build and a release pipeline for the dev environment. But I need a Test and production environment. How do I transform the shared config before releasing it to the test and production environment?</p>
