EntityType 'ApplicantPosition' has no key defined

Question

When running my first asp.net mvc application I got this error I thought that entity framework automatically would create the keys of column names that end with Id? isnt it

Answer 1

EF Code First can only infer that a property is a primary key if the property is called Id or Id (or if it is annotated with the Key attribute). So you need to extend your e.g. ApplicantImage with an ApplicantImageId or Id property etc.
