The document discusses Windows services, which are long-running executable applications that run without a user interface and can start automatically when Windows restarts. It describes how to manage services through the Services console and covers alternatives like Windows Task Scheduler. The document also introduces several frameworks for developing Windows services like Topshelf and Quartz.NET and provides examples of automated backup, event logging, SMS reminders, and using OneNote through a service.

- 2. What is a Windows Service? ▪ A long running executable application that runs in its own Windows Session ▪ Can be started automatically upon Windows restart, can be paused and stopped ▪ No user interface is shown
- 3. When to use Windows Services? ▪ Your program accepts incoming requests and connections (e.g. mail server, FTP server, et al.) ▪ If you need to do processing without an active user logged in ▪ Monitoring queues, file systems
- 4. Managing Windows Services: ▪ In Windows 8.1, hit WIN key and type “services.msc” ▪ In Windows 7/XP, Run -> “services.msc”

- 6. Windows Service Details ▪ Manage Startup Type ▪ Manage Service Status ▪ Manage Description ▪ Manage Security
- 7. Goal of Windows Service Development?
- 8. Alternatives to Windows Services: ▪ Windows Task Scheduler: – Ideal for nightly FTP retrieval – Hourly backup – Weekly Defrag ▪ Example (“Hello World”)
- 9. Building Services with Visual Studio ▪ Can be built using the “Windows Service” project type in Visual Studio ▪ Built with either C# or VB.NET ▪ Example (“File Creator”)
- 10. Topshelf ▪ http://topshelf-project.com/ ▪ Easier approach for developing Windows Services ▪ Can convert a Windows Console application into a Service (easy for debugging!) ▪ NUGET: – PM> Install-Package Topshelf ▪ Example (“File Creator Redux”)
- 11. Quartz.NET ▪ http://www.quartz-scheduler.net/ ▪ Enterprise Job Scheduler ported from the famous Java framework – Jobs implement the IJob interface – Jobs can be scheduled using Triggers – Jobs and triggers can be stored in a data store (e.g. relational database) ▪ NUGET: – PM> Install-Package Quartz
- 12. log4net ▪ http://logging.apache.org/log4net/ ▪ Enterprise logging framework built off of the famous Java framework log4j ▪ NUGET – PM> Install-Package log4net
- 13. Example #1 ▪ Automated Backup
- 14. Example #2 ▪ Event Viewer
- 15. Example #3 ▪ Automated SMS Resource Reminder
- 16. Example #4 ▪ Fun with OneNote
- 17. Example #5 ▪ SQL Server Job Store
