Entity Framework Core - Data annotation foreign keys are not generated?

Post by RobertK » Wed 12 Apr 2017 04:44

For Foreign keys columns: When you generate a class model with EFCore template, the foreign key property generated looks something like this

Code: Select all

public virtual long CountryId { get; set; }
Is it missing a foreign key data annotation or a databasegenerated data annotation?

Note: this is validation set to "data annotation" foreign keys just don't get generated?

The EF Core template generates fluent mapping for all classes and its properties (including foreign keys) in ModelName.cs.

If you want to add custom attributes:
1) double click diagram surface to open Model Settings and navigate to Model > Settings > Attributes > select the assembly (e.g.: System.ComponentModel.DataAnnotations.dll) with the needed attributes and make sure that the needed attributes (e.g.: ForeignKeyAttribute) are checked in the window below, press OK
2) select the needed attribute in the Attributes collection of a particular class property
