Assembly: System (in System.dll)
This counter is read-only, so any instance that is associated with the category cannot be removed.
The instance is not correctly associated with a performance counter.
An error occurred when accessing a system API.
The platform is Windows 98 or Windows Millennium Edition (Me), which does not support performance counters.
You can remove an instance only for a custom counter. All system counters are read-only, so attempting to remove one of them throws an exception.
To avoid a possible race condition when the performance counter shared memory is released, it is recommended that the method be called from the DomainUnload event handler.
To create a performance category instance, specify an instanceName on the PerformanceCounter constructor. If the category instance specified by instanceName already exists the new object will reference the existing category instance.
If the value for the InstanceLifetime property is Process and the performance counter category was created with .NET Framework version 1.0 or 1.1, an InvalidOperationException is thrown. Performance counter categories created with earlier versions use global shared memory, and the value for InstanceLifetime must be Global. If the category is not used by applications running on versions 1.0 or 1.1 of the .NET Framework, delete and recreate the category.
