Creating a Windows service Host


1. Open the solution attached here.

2. Add a new project > select Windows service from Visual C# > Windows template

3. Name it WinSrvHost and click OK

4. Go to the code view of Service1.cs, notice that you have been provided with a template that you can start working with. Notice that this class is derived from the ServiceBase class.

5. In the design view, go to property change the name and service name to ProdSrvHost.

6. Add reference to System.Servicemodel and ProductServiceLibrary project.

7. Create a ServiceHost, by add the  following code:
ServiceHost host = new ServiceHost(typeof(ProductService));

8. Override OnStart() method of ServiceBase
Add the following code

host.Open(); //use the one in the example

9. Override OnStop() method of ServiceBase
Add the following code

host.Close();//use the one in the example

10. Copy app.config from console host. Note that service metadata behavior is enabled (httpGetEnabled=true).

11. Add an installer - Go to the Design view of the Windows service host, right click on the designer > select Add Installer

12 Click on serviceProcessInstaller1 > in properties Change the user account to LocalSystem (Higher privilege built in windows account, not normally used in production, - it allows service to register http endpoint with Http.sys)

13. Build the project

14. To test it, you will need to install it.

15. Open Developer Command Prompt as an Administrator

16. Navigate to the folder where the installer is located (project's bin/Debug folder), and run the following command:

> installutil WindowsServiceHost.exe

17. If installation successful you should be able to see the service running in the services. To opens services type the following in the developer command prompt.

> services.msc

18. Locate the service and double click to open it > click start. This starts the service.

19. Open a browser and try accessing metadata. If you are able to access the metadata the service is up and running successfully. Just to verify if you are access the right service, stop the service, and try to access the metadata again. You should not be able to access the metadata page.

Test the client with Windows Service Host
20. First, we need to update the service reference of the client. To do this start the service again.

21 update the service reference of the client.

22. set the client project as the startup project > run the project.

CUMIPMT Cumulative interest payment function allows you to calculate the interest paid for a loan or from an investment from period A to period B. When getting a loan, CUMIPMT function can be used to calculate the total amount of interest paid in the first five months or from period 12 to period 20. A period can be a month, a week or two week.

BCG's Brand Advocacy Index

The Boston Consulting Group's (BCG) Brand Advocacy Index (BAI) is a metric developed to help companies measure the degree of customer advocacy for their brands. BAI focuses on the likelihood of customers to recommend a brand to others, which is a powerful indicator of brand strength and customer loyalty. Unlike other customer satisfaction or loyalty metrics, BAI emphasizes the importance of customer referrals and word-of-mouth marketing. BAI is calculated based on a survey where customers are asked about their willingness to recommend a brand to their friends, family, or colleagues. The responses are then used to compute a score, which ranges from -100 to 100. A higher BAI score indicates that a brand has more advocates who are likely to recommend the brand to others, while a lower score suggests that the brand has fewer advocates or even a higher number of detractors. BCG's research has shown that companies with higher BAI scores tend to experience higher growth rates and bett
