ExceptionCondition
PlatformNotSupportedException

The platform is Windows 98 or Windows Millennium Edition (Windows Me), which does not support this property.

The working set of a process is the set of memory pages currently visible to the process in physical RAM memory. These pages are resident and available for an application to use without triggering a page fault.

The working set includes both shared and private data. The shared data includes the pages that contain all the instructions that the process executes, including the process modules and the system libraries.

The following example starts an instance of Notepad. The example then retrieves and displays various properties of the associated process. The example detects when the process exits, and displays the process's exit code.

No code example is currently available or this language may not be supported.
