FreeSQL을 사용하는 일부 오픈 소스 프로젝트 :
DotNet은 패키지 추가 FreeSQL.provider.sqlite를 추가합니다

DotNet은 패키지 추가 FreeSQL.repository를 추가합니다
[ Transactional ]
public void Add ( ) {
var repo = ioc . GetService < BaseRepository < Tag > > ( ) ;
repo . DbContextOptions . EnableCascadeSave = true ;
var item = new Tag {
Name = "testaddsublist" ,
Tags = new [ ] {
new Tag { Name = "sub1" } ,
new Tag { Name = "sub2" }
}
} ;
repo . Insert ( item ) ;
} 참조 : ASP.NET Core의 TransactionalAttribute 및 UnitOfWorkManager 사용하여 다중 트랜잭션 전파를 달성하십시오.
