Some open source projects that use FreeSql:
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
