The inability to update a primary key has just pushed my entity framework project into the dumpster :*- i can do this in sql, so why can't i do it using the entity framework? update mytable set myprimarykey = "yes my primary key has changed.". No foreign key property. while it is recommended to have a foreign key property defined in the dependent entity class, it is not required. if no foreign key property is found, a shadow foreign key property will be introduced with the name <navigation property name><principal key property name> (see shadow properties for more information).. Ado.net entity framework and linq to entities https: first of all you cannot update the foreign keys in an entity--they are read-only. you must update the whole entity. my guess is that this approach keeps the data in the enties in the project exactly as what's in the database--a good thing..
Entity framework 6 not updating foreign key relation. ask question. up vote 0 down vote favorite. hello i have a strange issue here. i have a project model that has a foreign key to the company model. how to update record using entity framework 6? hot network questions. If so, i am confused why the foreign key is not changed at your side and you could copy the code above and just replace my entities with yours to see whether it would work. or you could try to assign the foreign key value to the foreign key property as: orderdnew.orderid = db.orders.find(2).orderid;.
