'Usage
 
Dim instance As StoreGeneratedIdGenerator

[DataContract()]
[DefaultExport(IsDefault=true,

[ExportMetadata(Name="IsFake", IsMultiple=false)]
public class StoreGeneratedIdGenerator : IIdentityIdGenerator, IIdGenerator

Remarks

This IdGenerator will automatically be used to provide a temporary property value for any new entities whose primary key is marked with the StoreGeneratedPattern="Identity" attribute in its entity model. You do not need to call EntityManager.GenerateId for these properties, as this key generation is done for you.

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.
