title: IIS Manager can't configure .NET Compilation on .NET 4 Applications
body: <p>i tried to configure the .NET Compilation Settings in the IIS Manager but all i see is an Error Message that tells me that there is an unrecognized element in the <code>web.config</code> file in <code>C:\windows\Microsoft.NET\Framework64\v.4.0.30319\config\</code>.</p>
  
  <p>A little bit strange for me is, that i get this error message on my Windows 7 System and also on a Windows Server 2008 R2.</p>
  
  <p>While googling around a little bit all i found is this blog entry <a href="http://olegtarasov.me/2010/09/nastrojka-iis-7-5-i-asp-net-4/" rel="noreferrer">http://olegtarasov.me/2010/09/nastrojka-iis-7-5-i-asp-net-4/</a>.
  I tried the <code>aspnet_regiis -i -enable</code> command but that was not the solution for me.</p>
