ef core 2.2 preview migration change












2















we just updated Entity Framework Core from 2.1 to 2.2.Preview3.
It seems that the migrator / modelbuilder changed and I am wondering if it is a bug or fix.



If have the following Entity:



public class User {
public string UserName { get; set; }
public Guid? PasswordGUID { get; set; }
[ForeignKey("PasswordGUID")]
public Password Password { get; set; }
}


The entity class Password has no navigation property to the entity class User.



With EfCore 2.1 the User Password relationship got the following lines in the modelsnapshot:



...
u.Property<Guid?>("PasswordGUID");
...
u.HasIndex("PasswordGUID");
...
u.HasOne("Password", "Password")
.WithMany()
.HasForeignKey("PasswordGUID");


Now after the update from EfCore 2.1 to 2.2.Preview3 (entity classes did not change) the model got the following changes:



...
u.Property<Guid?>("PasswordGUID")
.IsRequired();
...
u.HasIndex("PasswordGUID")
.IsUnique();
...
u.HasOne("Password", "Password")
.WithOne()
.HasForeignKey("PasswordGUID")
.OnDelete(DeleteBehavior.Cascade);


So as stated above, my question is: Is this correct? Do I now have to "revert" these changes in the modelBuilder Fluent API or is this a bug?



Sidenote: Strangely I noted with EfCore 2.1 the same behaviour, when I deleted the Attribute "[ForeignKey("PasswordGUID")]"
