leave the Navigation Property my problem is 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

While you can create a relationship based on this setup in SQL Server, current version of EF does NOT support creating associations based on candidate keys: In EF (3.5 and 4.0) FKs MUST point to Primary Keys. The only way to make this working is to create a new int field inside Note table (like UserId) and then create a new relationship between User.Id (PK) and Note.UserID (FK) and EF will happily create a association based on that for you. s

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.
