When you create an ePortal WCF Service Application (without Scaffolding) the project contains the CustomUserNameValidator.cs file to implement custom validation. This file is located in the App_Code folder. This file contains simple implementations of validators for Username/Password and Certificates. By default, these validators only check for null values. Refer to Programming in the Custom Validators for WCF Services Using Scaffolding for more information
When you build either a WCF Service Application (without Scaffolding) or a WCF ASP.Net Compatability Service Application, ePortal generates an interface containing the service contract and a class containing the service implementation. Refer to Creating a WCF ASP.Net Compatibility Service Application.
For more information on creating a WCF service application without scaffolding, refer to Creating a WCF Service Application.
In particular, ePortal generates the following files in the App_Code folder:
IService.cs - This file contains the interface defining the service contract.
Service.cs – This file contains the class which implements the service. Refer to Programming in the Service Implementation for WCF and WCF ASP.Net Services for more information.
Note: Since these generated service files are created on every build, they are not included as part of the project; therefore, the files do not appear in Solution Explorer unless you click the Show All Files button in the toolbar.
