I got an error message after updating my Entity Framework .edmx model:
Error 3007: Problem in Mapping Fragments starting at lines … : Non-Primary-Key column(s) [ColumnName] are being mapped in both fragments to different conceptual side properties - data inconsistency is possible because the corresponding conceptual side properties can be independently modified.
Finally I managed to solve the problem. I added a foreign key to a table, so Entity Framework generated an association. The association name was the same as the foreign key field name. Designer never removes CSDL objects, so these names were the same. I had to remove the entity field to make the model valid. Now it works fine.
could you please provide steps on this? I'm not sure how you implemented this..sorry..thanks!
ReplyDeleteIt was a long time ago. As far as I can remember just delete the field in the designer (if visible) or find that field in the XML and delete that manually.
ReplyDeleteIt is similar to UML: the reference will represent the relation instead of the field. Unfortunately you have to delete the previously created and useful field manually.
many thanks!
