SYMPTOMS

Consider the following scenario:
  • On a Windows Vista-based computer, you are running a Media Center Markup Language (MCML)-based application.
  • You switch to another application. Therefore, the MCML-based application is in the backstack.
  • The ApplicationContext.ReturnToApplication method is called.
In this scenario, you do not return to the original instance of the MCML-based application as expected. Instead, a new instance of the MCML-based application is started. Therefore, the application consumes extra resources when you restart it. If the application consumes lots of extra resources, this issue may affect system performance.
