WCF and HTTP Error 404.3


Once you create a WCF Service from Visual Studio 2008 and after publishing to IIS, when you browse your Service, you will receive HTTP 404.3 Error. But you will not find any discrepancies in IIS Configuration of the Service.



This is due to Windows Service of Microsoft .NET Framework 3.0 not fully installed (not activated the WCF Windows Services) and not because of Windows Service of IIS. So follow the below procedure if you are using Windows, Vista and for different operating systems, it is found in different locations.

Vista  : Control Panel -> Program and Features -> Turn on/ off Windows Features -> Microsoft.NET Framework 3.0

Now, Install the following Components.
  • Windows Communication Foundation HTTP Activation
  • Windows Communication Foundation Non-HTTP Activation
You can do the installation manually by running "ServiceModelReg.exe", which was found at %Windows%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\
