I have installed visual studio, sql server and sitecore 8 on my machine. the installation went well but when I run the website from the browser i got the below error message.
Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=184.108.40.206, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
Did a system and IIS restart but still getting the same error. Any idea why this issue occurs?
