Gets or sets the exit code that an application returns to the operating system when the application exits.
Assembly: PresentationFramework (in PresentationFramework.dll)
An application typically returns an exit code to the operating system to indicate whether an application exited successfully or not. An application exit code value of 0 (the default) is commonly used to indicate success. However, you are free to return exit code values that are appropriate to your application.
You can specify an exit code by handling the Exit event and setting with an appropriate value.
