'Usage

Remarks

This property is used only for Condition-Related Events (see EventType).

If the event notification is the result of a Refresh, the value of this property should be ignored.

It is server-specific whether this property will be True for a "new event". (A "new event" is any event resulting from the related condition leaving the Inactive and Acknowledged state.)

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
