Here is a basic Microsoft Web API 2 CRUD example. The Source code is [HERE] (this gives you the full directory and list of files, just File->Download to download the full zipped project). I used Visual Studio 2013 and local DB. I'm not using MVC or any ORM / Entity Framework stuff...this is a very basic example to help get you going.
You will need to change the database path in the web.config file.
