entity framework - accessing foreignkeytables in LINQto EF query -


i have foreign key tables in database(mysql). why these not accessible in linq ef? example have table shippinglocationscontacts, why table not become part of ef model? how can access these tables in linq ef?

i bet shippinglocationscontacts junction table. contains shippinglocationid , contactid (or similar names). ef feature. maps junction tables many many association between, in case, shippinglocations , contacts.

so contact has property shippinglocations , shippinglocation has property contacts.

you don't manipulate table directy. add items collections (like shippinglocation.contacts.add(contact) , ef insert record in junction table.
