Remarks
If you do not wish to use this generator for your Identity properties you will need to provide a stub or custom implementation of IIdentityIdGenerator.
The Entity Framework uses the StoreGeneratedPattern attribute to indicate properties whose value is provided by the data source after the row has been saved. The StoreGeneratedIdGenerator allows you to assign temporary values to these key fields, and will automatically map these temporary IDs to the real IDs assigned by the data source.
