Answer 1

The store-generated pattern is in the SSDL content of the EF model. Here's an example of how you can get the properties with identity specification:

var items = oc.MetadataWorkspace.GetItems(DataSpace.SSpace).OfType();
foreach (var entityType in items)
{
    var props = string.Join(",", entityType.Properties
                .Where(x => x.IsStoreGeneratedIdentity));
    Trace.WriteLine(string.Format("{0}: {1}", entityType.Name, props));
}

(where oc is an ObjectContext)
