title: How to check which ASP.NET Version was used for .aspx files
body: <p>I've got an old website which I have to recreate in PHP instead of ASP. The website was written in ASP.NET (.aspx files), and in order to display the website I have to state which ASP.NET version was used. Can I get that information out of the .aspx files?</p>
  
  <p>Thanks.</p>
  
  <p>EDIT: This is inside my webconfig file:</p>
  
  <pre><code>&lt;compilation debug="false"&gt;
     &lt;assemblies&gt;
        &lt;add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31CF2543AD364E11"/&gt;
     &lt;/assemblies&gt;
  &lt;/compilation&gt;
  </code></pre>
