How can I get rid of this run time EF error

Question

0.00/5 (No votes)

See more:

Additional information: The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: Saving or accepting changes failed because more than one entity of type 'Project.Models.CertiStaging; have the same primary key value. Ensure that explicitly set primary key values are unique. Ensure that database-generated primary keys are configured correctly in the database and in the Entity Framework model. Use the Entity Designer for Database First/Model First configuration. Use the 'HasDatabaseGeneratedOption" fluent API or 'DatabaseGeneratedAttribute' for Code First configuration.

What I have tried:

I have two database tables named Certi and CertiStaging, both has same primary key. I don't want to remove that primary key nor want to alter anything in my models. How can I get rid of that run time EF Error?

Sounds like you are trying to save data that conflicts the rules of the primary key uniqueness. Have a look at the data you are saving and see if there is a record of the same primary key values you are try to save. If so, the data is invalid so or you need to create a more prescriptive primary key to ensure record uniqueness or change the data you are saving.

Sounds Perfect. But how can i create a more prescriptive primary key to ensure record uniqueness or change the data I am saving.

On the database tables. Not your application.
