ADO.NET Entity Framework and identity columns

Is the Entity Framework aware of identity columns?

In C# you can do something like this to make it aware:

In your FooConfiguration.cs : EntityTypeConfiguration:

this.Property(x => x.foo).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);

Then to use it, just be sure to insert the item into the context and call context.SaveChanges() before using x.foo to get the updated auto-incremented value. Otherwise x.foo will just be 0 or null.
