title: Lint tool for web.config
body: <p>Greetings all,</p>
  
  <p>As someone new to ASP.Net, I have been modifying web.config files for web apps I use and frequently breaking the apps in the process. I'm wondering if there is some kind of "lint" tool for web.configs which will analyse and look for potential problems.  Perhaps this is infeasible given that each web.config is specific to its app, version of ASP.net etc, but I thought I would ask anyway.</p>
  
  <p>Thanks.</p>
