breeze - Include server side properties not mapped to entity framework entity -

we adding additional properties our objects on server not track in database. data gets returned client object materialized breeze not have property. how can add properties our objects return breeze not map them database store data?

example: widget class property - mapped database property b - has [notmapped] attribute not stored in database. calculated on fly server.

when object on client get: widget class = { property a: ko.observable(value a) }

property b missing.

when @ json returned server see:

widget class = { property a: value a, property b: value b }

properties notmapped attributes not part of metadata generated efcontextprovider, properties won't available in client side breeze entity. in js can extend client side entity , add property entitytype yourself. make sure value property correctly set when json object retrieved server.
