• Then solution explorer will created with following default files like IService1.cs and Service1.svc

• Delete those files and right click on solution explorer--> Add New Item--> Select Wcf Service template and name it as Calculator.

• Then two files created in Solution Explorer i.e. ICalculator.cs(ServiceContract) and Calculator.svc is a service file which is having inheritance from  ICalculator.cs

• Then write the following in ICalculator.cs(ServiceContract)

• Then modify method definitions as shown.

• Then our WCF Service is ready to run, press F5 or Run button this will lead you to the following screen.

• Then our service ready to check how its working, all the methods we wrote in service are visible here as shown.

• Then double click on any method which you want test. I'm going for Add() method. After double click on Add() method we will get method test screen as shown.

• You can check service by giving values of "a" and "b" in [Request Pane] and click on invoke you will get return value in [Response Pane].
