Could not load type from assembly "System.ServiceModel, version=, culture=neutral, publickeytoken=b77a5c561934e089" System.ServiceModel.Activation.HttpModule ".

It appears to be a problem with the version, because I am a version of the. Net framework4.0, compiled with VS 2010, how to load 3.0 of DLLs.

The reason for the Internet is that the local computer installed the. NET Framework 4.0 first, then installed the IIS7, so you should perform "Aspnet_regiis.exe-iru" to register. NET 4.0 into IIS.

Under the c:/windows/ found the aspnet_regiis.exe, open the CommandLine, execute "Aspnet_regiis.exe-iru", Information appears:
