Hi All, 

I am using Windows 10 for my developing WCF Data Service and i am getting below error:

Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

I have already done necessary configurations like HTTP Activation, etc. but no luck. Can anyone suggest me the solution or article to fix this?

Hi kodnil,

For this error, it seems to be related with .NET Framework. I suggest you try to re-register IIS by below command.

aspnet_regiis.exe /iru

You could refer below link for more information.
