I will go through what i've done so far step by step as below:
- created empty solution
- added a website WCFService
- deleted the Service and IService from the website
- added a WCF service library project to the solution
- added end points to the web.config
- did the same in app.config
- added a reference to the service library in the web application
- ctrl + F5

Look at the WF_Ledger.svc file in your web site project. It should only consist of one line. There'll be Service attribute containing "Services.WFAPILedger.WF_API_Ledger". WCF is looking for the "Services.WFAPILedger.WF_API_Ledger" class but not finding it. The namespace and class name need to either exist in the web site project or be a reference as you're trying to set up. You'll need to edit that Service attribute to match the service implementation class in the WCF service library project.
