IIS Manager can't configure .NET Compilation on .NET 4 Applications

Question

Hi,

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 web.config file in C:\windows\Microsoft.NET\Framework64\v.4.0.30319\config\.

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.

While googling around a little bit all i found is this blog entry http://olegtarasov.me/2010/09/nastrojka-iis-7-5-i-asp-net-4/. I tried the aspnet_regiis -i -enable command but that was not the solution for me.

Answer 1

Ok, i've got it.

The Problem is, that my systems a 64 Bit systems and the aspnet_regiis i've called was the 32 Bit Version. After calling aspnet_regiis from the Framework64 Directory everything was fine.
