Error 3004, mapping error with EF

Ok since my of my issues have been resolved,I was flying through the code, until now: I've now run into one I cant even find anything on Google for it. Here's the text of the error:

Error 3004: Problem in mapping

fragments starting at line 937:No mapping specified for properties StoreItem.ItemPrice in Set StoreItems. An Entity with Key (PK) will not round-trip when: Entity is type [psychoco_GodsCreationTaxidermyModel.StoreItem] F:\Projects\GodsCreationTaxidermySVN\GodsCreationTaxidermy.Data\GCTEntities.edmx 938 945 GodsCreationTaxidermy.Data

Of you need any code samples let me know

Solution

  • The error means that your table imported to the model contains additional column ItemPrice which is not mapped to your entity.
