Remarks

If you change a key property that is in a collection, the positional order (and index) of the property in the collection may change. The changed key property will be added to the beginning or end of the collection depending on the value of the mergeAppend attribute.

Note

The mergeAppend attribute is in the appropriate schema file in the section that corresponds to the class property. If the mergeAppend attribute is false, new items are added to the beginning of the collection; if the mergeAppend attribute is true, new items are added to the end of the collection.

You should be careful how you access a key property in a collection after the key property's value has changed. For example, if you change the value of a key property whose index is 4, the new index for the key property will be 0 if the mergeAppend attribute is false.

Note

You should be aware of this behavior when you create any custom schema and custom configuration files. You should not modify the mergeAppend attributes in the schema files that ship with IIS 7. You cannot modify the mergeAppend attribute by using the WMI provider for IIS 7.

The mergeAppend attribute affects the following ConfigurationSectionWithCollection class properties that ship with IIS 7. The table lists these properties and their corresponding schema files. In all these cases, the schema files that ship with IIS 7 specify false for the mergeAppend attribute.

Class	Property	Schema file
AuthorizationSection	`Authorization`	ASPNET_Schema.xml
CachingSection	`Profiles.Profiles`	IIS_Schema.xml
DefaultDocumentSection	`Files.Files`	IIS_Schema.xml
HandlersSection	`Handlers`	IIS_Schema.xml
HttpHandlersSection	`HttpHandlers`	ASPNET_Schema.xml
