my solution. I found these links: Good explination Short answer About this error: Error 1 Error 3007: Problem in Mapping Fragments starting at lines 89, 94: Non-Primary-Key column(s) [Person_ID] 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. Their Answer: I agree with their conclusion that by simply deleting the Scalar Property Person_ID and leave the Navigation Property my problem is entity framework error 11007 entity type is not mapped fixed. However this is not very scalable since I am dynamically building my database and my entity is updated very often. I dont want to have to go through and clean up my entity every time I update it. My Question: Is there a way to fix the error by correcting the way EF builds the entity? Or is there a way to remove the Scalar Property through code? Perhaps there is even a few options that I am overlooking. entity-framework entity-relationship share|improve this question asked Sep 2 '09 at 19:29 johnnywhoop 539419 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote accepted My experience with EF v1 is similar to yours. When the EDM is generated incorrectly and you can't work around the issue, you have to manually edit the EDM. EF v.Next (Entity Framework v4 I believe) will support "Code Only" Entity Data Models, and the EDM designer is supposed to be much better. One or the other improvement should make our lives easier. Until then... share|improve this answer answered Sep 3 '09 at 13:23 Dave Swersky 28.6k451104 add a comment| up vote 5 down vote Try to remove foreign property column from Entity set using entity model design it will solve your problem For example We have two tables one is customer and other one is order, using entity model design we added ass

Dec 15, 2014 12:12 AM|Kevin Shen - MSFT|LINK Hi sudesh456, It seems that you did in the wrong way in configuring the relationship between two entities in your project. In addition, here is a similar issue which may give you right direction: http://stackoverflow.com/questions/1015925/entity-framework-problem-in-mapping-fragments-error-help-me-understand-the I suggest that you should check it first,if it still working ,please post your code about your entity and how did you configure the relationship.

database. EF treats everything—and I mean everything—as an object; the foreign key fields by which objects are related aren’t even exposed in the generated code. But I’m getting ahead of myself http://encodo.com/en/blogs.php?entry_id=163 a bit. We wanted to figure out the most elegant way of mapping what we are going to call enumerated associations in EF. These are associations from a source table to a target table http://blogs.msmvps.com/kevinmcneish/2009/05/18/entity-framework-quot-problem-in-mapping-fragments-quot-error/ where the target table is a lookup value of type int. That is, the enumerated association could be mapped to a C# enum instead of an object. We already knew what we wanted the entity framework solution to look like, as we’d implemented something similar in Quino, our metadata framework (see below for a description of how that works). The goals are as follows: Properties of the enumerated type are stored in the database, including its identifier, its value and a mapping to translations. Relations to the enumerated value are defined in the database as constraints. The database is therefore internally consistent C# code entity framework error can work with an enumerated type rather than a sub-object; this avoids joining the enumerated type tables when retrieving the main object or restricting to the enumerated type’s value.EF encourages—nay, requires—that one develop the application model in the database. A database model consists of tables, fields and relationships between those tables. EF will map those tables, fields and relationships to classes, properties and sub-objects in your C# code. The properties used to map an association—the foreign keys—are not exposed by the Entity Framework and are simply unavailable in the generated code. You can, however, add custom code to your partial classes to expose those values[1]: return Child.ParentReference.ID;However, you can’t use those properties with LINQ queries because those extra properties cannot be mapped to the database by EF. Without restrictions or orderings on those properties, they’re as good as useless, so we’ll have to work within EF itself. Even though EF has already mapped the constraint from the database as a navigational property, let’s add the property to the model as a scalar property anyway. You’ll immediately be reprimanded for mapping the property twice, with something like the following error message: Error 3007: Problem in Mapping Fragments starting at lines 1383, 1617: Non-Primary-Key column(
add another entity that is related in the database to the first entity, Visual Studio will give you a "Problem in Mapping Fragments" error. For example, if you add a Northwind database Orders table using the EDM Update Wizard, it produces an entity that looks has an EmployeeID property that corresponds to the EmployeeID foreign key column of the Orders table. Next, if you add a Northwind database Employees table using the EDM Update Wizard, an Employees property gets added to the bottom of the Orders entity under Navigation Properties and a relationship between the Orders and Employees entities is shown on the diagram. However, there is still an EmployeeID property on the Orders entity. This is what causes the "Problem in Mapping Fragments" error. In order to get around this error, you can simply remove the redundant EmployeeID property from the Orders entity by right-clicking it in the designer and selecting Delete from the shortcut menu.
