Another different:-
1. The very basic point is that you need to select a "WCF Service Application" template under the WCF project type at the time of project creation. In other words when you create the project from File >> New >> Project, select the WCF as project type from the left side of the screen and select "WCF Service Application" from the template. Select your desired location and provide an appropriate name for your project and press the "OK" button.
2. For a WCF Service Library you need to select "WCF Service Library" template at the time of project creation.
3. In the Service Application we have a service contract i.e. IService1 for the service implementation and Service1 as a Web.config file.
4. In the Service Library we also have a service contract i.e. IService1 for the service implementation and Service1 as an App.config file for the configuration (instead of web.config as in the Service Application).
Happy Coding,
