Mirroring is not working for site

Hi , 

I have created the mirrioring for site. But while trying to run the Mirririing service it is throwing below error:


Failed to check system, the reason is
Error executing task "SourcePOC": Mirroring Source: Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
Could you please help me to fix the issue.
