check constraint entity framework

Question

IN EF can I add a check constraint so if my CustomerNotes entity has a boolean "FollowUpRequired" property I force user to enter a valid future date in the "FollowUpDate" property?

Answer 1

EF Core 3.0 supports entity.HasCheckConstraint() now.

To take Ryan's example:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<SomeTable>(entity =>
        entity.HasCheckConstraint("CK_SomeTable_SomeColumn", "[SomeColumn] >= X");
}
