🚀 Quick start

dotnet add package FreeSql.Provider.Sqlite

static IFreeSql fsql = new FreeSql.FreeSqlBuilder()
  .UseConnectionString(FreeSql.DataType.Sqlite, @"Data Source=document.db")
  .UseAutoSyncStructure(true) //automatically synchronize the entity structure to the database
  .Build(); //be sure to define as singleton mode

class Song {
  [Column(IsIdentity = true)]
  public int Id { get; set; }
  public string Title { get; set; }
  public string Url { get; set; }
  public DateTime CreateTime { get; set; }
  
  public ICollection<Tag> Tags { get; set; }
}
class Song_tag {
  public int Song_id { get; set; }
  public Song Song { get; set; }
  
  public int Tag_id { get; set; }
  public Tag Tag { get; set; }
}
class Tag {
  [Column(IsIdentity = true)]
  public int Id { get; set; }
  public string Name { get; set; }
  
  public int? Parent_id { get; set; }
  public Tag Parent { get; set; }
  
  public ICollection<Song> Songs { get; set; }

  var item = new Tag {
    Name = "testaddsublist",
    Tags = new[] {
      new Tag { Name = "sub1" },
      new Tag { Name = "sub2" }
    }
  };
  repo.Insert(item);
}
