Working with WCF Data Services and Entity Framework


In this section, we will discuss how we can create a WCF Data Service using Entity Framework and the AdventureWorks database. To add a WCF Data Service application to an existing web application, follow these steps:

  1. Create an ASP.NET application:

  2. Create a new Entity Data Model and name it AdventureWorks:

  3. Select Code First from database:

  4. In the Entity Data Model Wizard dialog, specify the data connection properties and click Next:

  5. Next, choose the database objects you want to be part of the Entity Data Model:

  6. Now, right-click on the project in the solution explorer window and select Add New Item.

  7. Select WCF Data Service from the list of the templates displayed, specify a name, and click OK.

And, you are done! At first glance, the WCF Data Service class looks like this:

using System.Data.Services;
using System.Data.Services.Common;
namespace WCFDataServices
{
    public class CurrencyDataService : DataService< /* TODO: put
