title: How to get IIS version through .NET
body: <p>I got web app which uses ms mvc. I'm still living in stone age - using IIS5. I'm not aware how to make URL`s clean in it (without .aspx postfix) and i do not care, cause production environment won't use 5th version. But it's irritating when testing app manually.</p>
  
  <p>I need a way how to make those URL`s clean or to get version of IIS inside in app to determine if .aspx postfix is needed.</p>
