title: How to run ASP.NET MVC 1 and 2 on the same machine?
body: <p>I have developed a site using MVC 1, then updated to MVC 2 Preview 1 and now when I open the site I found the error:</p>
  
  <blockquote>
    <p><strong>The project type is not supported by this installation.</strong></p>
  </blockquote>
  
  <p>Since I want to stick this project with the version 1, but also I want to create my new projects with version 2, how can I resolve this already made project to run with ASP.NET MVC 1 while having installed version 2?</p>
  
  <p>I guess the solution goes in the path of resolving some references in web.config, but I don't know exactly what.</p>
