title: Transform web.config for Azure Website Deployment for each release environment
body: <p>In Visual Studio Team Services (was Visual Studio Online), I have three release environments each with an Azure Website Deploy step.</p>
  
  <p>I can transform the web.config for the build step by specifying the "BuildConfiguration" variable (e.g. Uat) which picks up the Web.Uat.config.</p>
  
  <p>However I have multiple release environments that use this build configuration which all need to transform the web config (e.g. Dev,Test,Uat,Live). </p>
  
  <p>Is it possible to specify the the web config transform to use for each release environment before the Azure Website deploy step?</p>
  
  <p>Note: I realise that simple appsettings and connectionstrings can be specified in the Azure Portal under "All Settings" for the website but I need to do much more than transform these simple settings and already have configured the web config transforms for each environment within my solution</p>
