Entity Framework seeding complex objects? -

i trying figure out how seed complex entity framework code first object. code have allows me insert simple objects there has way more complex items, i.e. address adresstype field.

context.addresstypes.addorupdate(          p => p.name,          new addresstype { name = "original" },          new addresstype { name = "shipping" },          new addresstype { name = "billing" }         ); context.addresses.addorupdate(          => a.address1,          new address           {           address1 = "1234 west main",           city = "hannibal",           region = "mo",           postalcode = "12345",           country = "usa",           type = context.addresstypes.where(a=>a.name=="original")           }); 

but while can "find" addresstype id can't "where" name equals. find work except can not guarantee id each seed , want base on name instead.

any suggestions on how this? tia

solution: added reference system.linq seed class. able clause.
