When this method completes, it returns an map/dictionary containing string key/untyped value pairs. If you use Asynchronous programming, the result type is a map or dictionary of these key-value pairs, keyed by string names. (You can use APIs of IMap for C++, APIs of IDictionary<String,Object> for .NET.)

Remarks
This method is used to access the extended properties for the contact store, not for individual contacts. A common scenario is to use the contact store's extended properties to store revision numbers for the local contact store and a remote contact store in and then using GetChangesAsync to synchronize the two stores. To access extended properties to individual contacts, see GetExtendedPropertiesAsync.
