-    3.  Step 3 – Creates a <!--zz <xref:System.ServiceModel.ServiceEndpoint>--> ` System.ServiceModel.ServiceEndpoint` instance. A service endpoint is composed of an address, a binding, and a service contract. The <!--zz <xref:System.ServiceModel.ServiceEndpoint>--> ` System.ServiceModel.ServiceEndpoint`  constructor therefore takes the service contract interface type, a binding, and an address. The service contract is `ICalculator`, which you defined and implement in the service type. The binding used in this sample is <xref:System.ServiceModel.WSHttpBinding> which is a built-in binding that is used for connecting to endpoints that conform to the WS-* specifications. For more information about WCF bindings, see [WCF Bindings Overview](../../../docs/framework/wcf/bindings-overview.md). The address is appended to the base address to identify the endpoint. The address specified in this code is "CalculatorService" so the fully qualified address for the endpoint is `"http://localhost:8000/GettingStarted/CalculatorService"` Adding a service endpoint is optional when using .NET Framework 4.0 or later. In these versions, if no endpoints are added in code or configuration, WCF adds one default endpoint for each combination of base address and contract implemented by the service. For more information about default endpoints see [Specifying an Endpoint Address](../../../docs/framework/wcf/specifying-an-endpoint-address.md). For more information about default endpoints, bindings, and behaviors, see [Simplified Configuration](../../../docs/framework/wcf/simplified-configuration.md) and [Simplified Configuration for WCF Services](../../../docs/framework/wcf/samples/simplified-configuration-for-wcf-services.md).
