title: How can I make a web.config tranformation on the TFS2017 for ASP.NET application
body: <p>I have a continuous integration process running in my tfs2017. What I don't know is how to configure the .config file in build time to reflect the proper web.config per environment. Is there also anyway to achieve this by just making a configuration per environment? not with Tokenization</p>
  
  <p>I have friends that recommend me to follow their steps but I am seeing that they can configure the build definition through the visual studio, but in my case every time I am clicking in a new Build Definition redirects me to the tfs online. Also they have a magic step Items to Build where they choose the definitions to transform.</p>
