Consider the following scenario:

•	You create a managed service that uses the Microsoft .NET Framework 2.0.
•	You run the managed service on a computer that is running the .NET Framework 2.0.

In this scenario, the managed service is not stopped in a timely manner on the computer when the operating system shuts down. Therefore, you may experience delays when the operating system shuts down.

When you shut down the operating system, the OnShutdown method is called. However, the OnShutdown method does not change the system state to the Stop state. This behavior causes the service to appear unresponsive. Therefore, the shutdown process is delayed.
