I have somewhat of a problem. My old webserver (windows 2003) have been replaced, with a 2008 R2. I have been given an admin account on it, and can do whatever I want, but I am no expert on this area. I configured the roles to have application developement and Web server (iis7).
BUT, my website runs .NET4, and the role only installed 3.5. So I have attempted to install .NET4 manually, on the server. My problem is, my website will not work on it, due to the System.ServiceModel section in my web.config. I have made sure it runs in .NET4 application pool.
I assume this is a WCF problem, but I can't grasp how to solve it. I have tried everything I found on google. aspnet_regis, ServiceModelReg.exe and so on. I have even tried re-installing the webserver role, but I still get this error, everytime I try to enter the sites setup.
I'm hoping there are some experts here, who know how to fix this.
Apparently IIS7 needs a System.WebServer section, even if it is empty. Adding the following to my web.config file fixed my problem.
<system.webServer>
</system.webServer>
