framework - “Problem in mapping fragments”-error. Help me understand the explanations of this error up vote 40 down vote favorite 5 Error 3007: Problem in Mapping Fragments starting at lines 186, 205: Non-Primary-Key column(s) [WheelID] 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. I found several entity framework error 3007 problem in mapping fragments places on the web describing this error, but I simply don't understand them. (confused smiley goes here) One Two Three Four There is something pretty fundamental here, I must be missing. Can you explain it, so that I understand it? Maybe using my real life example below? Foreign key 1:N Wheels.Id -> Slices.WheelId I add them to entity framework, and WheelId is not visible in the Slices-entity. Doing some workaround (deleting the relationship from the db before adding tables to EF - then re-creating it and updating EF) I managed to get the WheelId to stay in Slices, but then I get the error mentioned at the top. entity-framework share|improve this question edited Aug 24 '12 at 9:42 AakashM 43.1k998155 asked Jun 19 '09 at 0:53 Kjensen 4,0762568125 add a comment| 9 Answers 9 active oldest votes up vote 37 down vote accepted Since Slices.WheelId is an FK, you cannot expose it in your client model, period. There are ways to get the value, though. var wheelId = someSlice.Wheels.ID; Update In EF 4 you can do this by using FK Associations instead of independent associations. share|improve this answer edited Au

Make sure both entities are present in the conceptual model (visible from the EDMX designer), and that the association between them is mapped properly to the one in your storage model.

Some types of changes are not propagated automatically to the CSDL by the wizardin order to avoid breaking any customized CSDL. I have a tool that can help you to get an overview over differences between the layers (entities, members, associations, etc) that are missing/unmapped or with different attributes and to selectively synchronize any such differences. I have described the reporting aspect of it better in this blog post / screencast: http://huagati.blogspot.com/2010/08/using-model-comparer-to-generate.html Kristofer - Huagati Systems Co., Ltd.
