title: Difference between Microsoft .NET Framework Version vs ASP.NET Version on Server Error Page
body: <p>In an ASP.NET application, if a server error is encountered, an error page is displayed. On the bottom of this page is a line which reads:</p>
  
  <pre><code>Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.6.81.0 
  </code></pre>
  
  <p>What exactly does the "Microsoft .NET Framework Version" and "ASP.NET Version" refer to? It's my understanding that the "Microsoft .NET Framework Version" is the CLR version. However, I can't seem to find a decent explanation of this anywhere. Thank you!</p>
