Remarks
The order of the values in the ICollection is unspecified, but it is the same order as the associated keys in the ICollection returned by the Keys method.
The returned ICollection is not a static copy; instead, the ICollection refers back to the values in the original HybridDictionary. Therefore, changes to the HybridDictionary continue to be reflected in the ICollection.
Retrieving the value of this property is an O(1) operation.
