I have a ASP .NET MVC4 application using Entity framework CodeFirst and I want to expose its data with WCF data services. I don't know where and how to begin.
Could you give me ways to follow ?
My final goal is to deploy this service on Windows Azure PaaS.
Create a new Web Application project within your solution and add a new WCF DataServices item.
This WCF DataSercices should reference the same business layer as the one you might use within your controllers
/model builders
in your ASP .Net MVC4 application.
Then have a look here to learn about how to deploy on Azure.
