Qualifiers are name/value pairs used by the WMI infrastructure. Most of the necessary WMI qualifiers are automatically generated by the WMI.NET Provider Extensions infrastructure. Many of the other attributes cause the generation of WMI qualifiers. However, this attribute lets you manually associate additional qualifiers should you need to do so.

To learn more about this topic, see WMI Qualifiers in the WMI SDK on MSDN online.

The following example demonstrates using the ManagementQualifier attribute to indicate that a class implements a WMI association class. In this case, the qualifier has a DisableOverride flavor that specifies that the effect of the qualifier cannot be overridden in subclasses.

[ManagementQualifier("Association", Flavor = ManagementQualifierFlavors.DisableOverride)]
