If you open your WCF/ svc file in your localhost through browser and it just display blank page then what might happen is you don’t have handler associated with svc extension
To verify it, go to your IIS and go to IIS Handler Mappings and try to find an svc extension entry, but if you couldn’t find extension SVC exists on the list, then you can remap/re-add the svc extension by running
C:\Windows\Microsoft.NET\Framework64\v3.0\Windows Communication Foundation\ServiceModelReg.exe –i
*if you are still using 32 bit then you just need to replace Framework64 with Framework
