CounterSet.CreateCounterSetInstance now throws InvalidOperationException if instance already exists

  • Article

Starting in .NET 5, CounterSet.CreateCounterSetInstance(String) throws an InvalidOperationException instead of an ArgumentException if the counter set already exists.

Change description

In .NET Framework and .NET Core 1.0 to 3.1, you can create an instance of the counter set by calling CreateCounterSetInstance. However, if the counter set already exists, the method throws an ArgumentException exception.

In .NET 5 and later versions, when you call CreateCounterSetInstance and the counter set exists, an InvalidOperationException exception is thrown.

Version introduced

5.0

If you catch ArgumentException exceptions in your app when calling CreateCounterSetInstance, consider also catching InvalidOperationException exceptions.

Note

Catching ArgumentException exceptions is not recommended.
