When to Implement
An implementation of this interface is provided by CLSID_InMemoryPropertyStore. Users should never need to implement it themselves.CLSID_InMemoryPropertyStore implements IPropertyStoreCache as well as IPropertyStore and other interfaces so that it can store additional information (PSC_STATE) about each of the properties. This information can be useful for property handler implementers. It can also be useful in other scenarios where a cache of property values is needed.
