below links are very much helpful you can refer to it : http://blogs.msdn.com/b/webtopics/archive/2010/04/28/system-typeloadexception-for-system- servicemodel-activation-httpmodule-in-asp-net-4.aspx

 http://social.msdn.microsoft.com/Forums/en/wcf/thread/39571e42-aca7-469d-8c68-aa59c2da4fcc

This error can occur when IIS is installed after installing .NET Framework 4, or if the 3.0 version of the WCF Http Activation module is installed after installing IIS and .NET Framework 4.

To resolve this problem, you must use the ASP.NET IIS Registration Tool (Aspnet_regiis.exe,) to register the correct version of ASP.NET. This can be accomplished by using the –iru parameters when running aspnet_regiis.exe as follows:

aspnet_regiis.exe -iru

OR

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

good luck
