安装

Install-Package FreeSql.Repository

示例代码

static IFreeSql fsql = new FreeSql.FreeSqlBuilder()
    .UseConnectionString(FreeSql.DataType.MySql, connectionString)
    //Automatically synchronize the entity structure to the database.
    .UseAutoSyncStructure(true) 
    //Be sure to define as singleton mode
    .Build(); 

using (var uow = fsql.CreateUnitOfWork())
{
  var songRepo = fsql.GetRepository<Song>();
  var userRepo = fsql.GetRepository<User>();
  songRepo.UnitOfWork = uow; //Manually bind unit of work
  userRepo.UnitOfWork = uow;

  songRepo.Insert(new Song());
  userRepo.Update(...);

  uow.Orm.Insert(new Song()).ExecuteAffrows();
  //Note: uow.Orm and fsql are both IFreeSql
  //uow.Orm CRUD and uow are the same transaction (understood as temporary IFreeSql)
  //fsql CRUD and uow are not in the same transaction

  uow.Commit();
}
