如何使用Entity Framework Core创建连接表？

public class StudentCourse
{
    public int StudentId { get; set; }
    public Student Student { get; set; }

    public int CourseId { get; set; }
    public Course Course { get; set; }
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<StudentCourse>()
        .HasKey(sc => new { sc.StudentId, sc.CourseId });

    modelBuilder.Entity<StudentCourse>()
        .HasOne(sc => sc.Student)
        .WithMany(s => s.Courses)
        .HasForeignKey(sc => sc.StudentId);

    modelBuilder.Entity<StudentCourse>()
        .HasOne(sc => sc.Course)
        .WithMany(c => c.Students)
        .HasForeignKey(sc => sc.CourseId);
}
