FIX: The performance counters that monitor an application stop responding when the application exits and restarts and you receive the System.InvalidOperationException exception on a computer that is running .NET Framework 2.0
You add performance counters to monitor an application on a computer that is running the Microsoft .NET Framework 2.0. The application exits and then restarts. However, the values in the performance counters do not change and you receive a System.InvalidOperationException exception together with the following exception error message:
Instance '< Instance name of the performance counter>' already exists with a lifetime of Process. It cannot be recreated or reused until it has been removed or until the process using it has exited.
This problem occurs because the handles are not cleaned up after the process that owns the performance counters exits. Then, the Common Language Runtime (CLR) throws the exception described in the symptoms section.
