IPropertyMapper Interface

The result of a $select and $expand projection is represented as an ISelectExpandWrapper instance. That instance can be projected into an IDictionary<TKey, TValue> instance by calling ToDictionary. That method will use the function to construct an IPropertyMapper that will map the property names in that projection to the keys in the returned IDictionary<TKey, TValue>. The main purpose of converting an ISelectExpandWrapper instance into an IDictionary<TKey, TValue> (using the method mentioned above) is to allow changing the names of the properties in the IEdmStructuredType that will be used during the serialization of the $select and $expand projection by a given formatter. For example, to support custom serialization attributes of a particular formatter.
