When running a new installed Sitefinity site I got the following error:
Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral

I noticed this was a issue that was reported in the forum but only with the beta 2 version of Sitefinity 4 (http://www.sitefinity.com/devnet/forums/sitefinity-4-x/general-discussions/could-not-load-type-system-servicemodel-activation-httpmodule-sitefinity-4-0-beta-2.aspx).
I have the same error in Sitefinity 4.1.

The solution that was mentioned in the beta topic solved my problem as well: 
use aspnet_regiis of .NET framework 4 to reinstall .NET in IIS.

Just wanted to post this, it might help someone else.


Cheers,

Rob

Hello Rob,

You are right the solution is to use the  aspnet_regiis.exe -iru command. Mostly the problem appears if you have installed the .NET 3.5.1 WCF HTTP Activation feature after the installation of .NET 4 framework on your server and in order to resolve the issue you need to re-register the .NET 4 framework of ASP.NET with IIS by using the ASP.NET IIS Registration Tool.

All the best,
