Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.

Determines whether the package contains a metadata property with the specified name.

Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.

Returns an enumerator that iterates through the collection.

Removes metadata properties satisfying the specified predicate.

Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.

Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties(FuncMetadataProperty, Boolean, PropertyValue) and UpdateProperties(FuncMetadataProperty, Boolean, PropertyValue). If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package.

Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
