What is the replacement for hasRequired with EF core?

Question

With Entity Framework we had HasRequired on a field. What is the alternative replacement for that with EF core?

I tried with HasRequired but it throws error.

Check out the Required and Optional Relationships in the EF Core Documentation.

Specifically I think you'll want something like:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<MyEntity>()
        .HasOne(p => p.Relationship)
        .IsRequired();
}

Or something like that - you haven't given much information to go on
