Mam troszkę wolnego czasu i chciałem chociaż w podstawowym stopniu ogarnąć NHibernate ale pojawił się problem z konfiguracją za pomocą fluent api. Zrobiłem wszystko jak w linku:
https://github.com/FluentNHibernate/fluent-nhibernate/wiki/Getting-started
Aplikaca konsolową netcoreapp2.1, VS 2017. Podczas uruchamiania aplikacji dostaję błąd:
NHibernate.HibernateException

Inner Exception 1:

Inner Exception 2:
HibernateException: The DbCommand and DbConnection implementation in the assembly System.Data.SqlClient could not be found. Ensure that the assembly System.Data.SqlClient is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use <qualifyAssembly/> element in the application configuration file to specify the full name of the assembly.
Z EF Core nie ma żadnych problemów, jeśli baza nie istnieje to ef ją sobie tworzy. NHibernate nie wspiera core 2.1 czy ja coś źle skonfigurowałem? Podczas debugowania błąd występuje w linijce new SchemaExport(cfg).Execute(true, true, false);
private static ISessionFactory CreateSessionFactory()
{
const string connectionString = "Data source=(LocalDb)\\MSSQLLocalDB;Database=NHibernateTest;Integrated Security=True";
var sqlConfiguration = MsSqlConfiguration.MsSql2012
.ConnectionString(connectionString)
.ShowSql();
Action<Configuration> config = cfg =>
new SchemaExport(cfg)
.Execute(true, true, false);
return Fluently.Configure()
.Database(sqlConfiguration)
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>())
.ExposeConfiguration(config)
.BuildSessionFactory();
}
