Improve Getting Started Guide by removing inconsistencies in service names (dotnet#9659)

* Update how-to-host-and-run-a-basic-wcf-service.md

- Fixed formatting of Important section.
- Fixed inconsistency with different baseAddress in csharp and vb example (also aligned to what is used in other steps)
- Updated instruction how to verify that your service is running.

* Update how-to-host-and-run-a-basic-wcf-service.md

- Incorporate instructions how to disable Start WCF Service Host when debugging to avoid conflicts.

 **Step 3** – Creates a <xref:System.ServiceModel.Description.ServiceEndpoint> instance. A service endpoint is composed of an address, a binding, and a service contract. The <xref:System.ServiceModel.Description.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](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"`.
 
-    > [!IMPORTANT]
-    > Adding a service endpoint is optional when using .NET Framework 4 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](specifying-an-endpoint-address.md). For more information about default endpoints, bindings, and behaviors, see [Simplified Configuration](simplified-configuration.md) and [Simplified Configuration for WCF Services](./samples/simplified-configuration-for-wcf-services.md).

 **Step 4** – Enable metadata exchange. Clients will use metadata exchange to generate proxies that will be used to call the service operations. To enable metadata exchange create a <xref:System.ServiceModel.Description.ServiceMetadataBehavior> instance, set it’s <xref:System.ServiceModel.Description.ServiceMetadataBehavior.HttpGetEnabled%2A> property to `true`, and add the behavior to the <xref:System.ServiceModel.Description.ServiceDescription.Behaviors%2A> collection of the <xref:System.ServiceModel.ServiceHost> instance.
 
 **Step 5** – Open the <xref:System.ServiceModel.ServiceHost> to listen for incoming messages. Notice the code waits for the user to hit enter. If you do not do this, the app will close immediately and the service will shut down.Also notice a  try/catch block used. After the <xref:System.ServiceModel.ServiceHost> has been instantiated, all other code is placed in a try/catch block. For more information about safely catching exceptions thrown by <xref:System.ServiceModel.ServiceHost>, see [Use Close and Abort to release WCF client resources](samples/use-close-abort-release-wcf-client-resources.md)

-> Edit App.config in GettingStartedLib to reflect the changes made in code:
-> 1. Change line 14 to `<service name="GettingStartedLib.CalculatorService">`
-> 2. Change line 17 to `<add baseAddress = "http://localhost:8000/GettingStarted/CalculatorService" />`
-> 3. Change line 22 to `<endpoint address="" binding="wsHttpBinding" contract="GettingStartedLib.ICalculator">`
+> When you add a WCF Service Library, Visual Studio can host it for you when you debug by starting a service host. To avoid conflicts you can disable this. 
+> 1. Open Project Properties for GettingStartedLib.
+> 2. Go to **WCF Options** and uncheck **Start WCF Service Host when debugging**.
 
 ## Verify the service is working
 
 1. Run the GettingStartedHost console application from inside Visual Studio.
 
    The service must be run with administrator privileges. Because Visual Studio was opened with administrator privileges, GettingStartedHost is also run with administrator privileges. You can also open a new command prompt using **Run as administrator** and run service.exe within it.
