Add a Class Library project to the solution. Call this new project EnrollmentEntities. Move the Enrollment.tt template from the EnrollmentData project to the EnrollmentEntities project. Add a reference to System.Runtime.Serialization. Add a project reference in the EnrollmentData project to the EnrollmentEntities project. Because we ve moved the Enrollment.tt template file we need to edit it to change the reference to the .edmx file for the model. Edit the Enrollment.tt template and change the line string inputFile = @"Recipe5.edmx" to string inputFile = @"..\EnrollmentData\Recipe5.edmx". You may have named your .edmx file something else, if so, make the changes so that the relative path is correct to your .edmx file. Edit the Enrollment.Context.tt template (which should still be in the EnrollmentData project) and add using EnrollmentEntities; after each <autogenerated> comment section. This will put the using statement in each generated file. Add a WCF Service Application project to the solution. Name the new service EnrollmentService. Add a reference to System.Data.Entity. Add project references to EnrollmentEntities and EnrollmentData. Copy the <connectionStrings> section from the App.Config file in EnrollmentData to the Web.config. Change the IService1.cs file to reflect the new IService1 interface in Listing 916. Change the IService1.svc.cs file to reflect the new implementation of the IService1 interface in Listing 9-17.
