title: Do I need to re-register .NET 4.0 with IIS 7 after installing .NET 4.5?
body: <p>I'm running IIS 7.0 on Windows Server 2008. It previously had .NET 4.0 installed with Application Pools for ASP.NET v4.0 and ASP.NET v4.0 Classic.</p>
  
  <p>I've now installed .NET 4.5 (v4.0.30319) and I know that .NET 4.5 is an "in place upgrade", but do I need to re-register .NET 4.0 with IIS?</p>
  
  <p>e.g. <code>C:\Windows\Microsoft.NET\Framework\v4.0.30319&gt;aspnet_regiis.exe -ir</code></p>
