Symptoms

Consider the following scenario:

  • You run an application in Windows Embedded Compact 7.

  • The application creates an instance of a custom user control in Silverlight for Windows Embedded.

  • You change the visual state of the user control.

  • You remove the user control.


In this scenario, a memory leak occurs. When this issue occurs for some time, the system may run out of memory.

Notes

  • The visual state is the way the user control appears in a particular state.

  • You can attach the Resource Leak Detector tool to the application to detect the memory leak.
