NHibernate 5–Async/await

With all the fuzz about .NET Core I almost forgot that NHibernate 5 was released a month ago.

One the things I was waiting for was the introduction of async/await to optimize IO bound methods. And after waiting for a loooooong time it’s finally there:

	// Usage ICriteria.ListAsync<T>()
	var customers = await session.CreateCriteria<Customer>().ListAsync<Customer>();
	// Usage ICriteria.UniqueResultAsync<T>()
	var customer = await session
	.CreateCriteria<Customer>()
	.Add(Restrictions.Eq("Name", "Ayende"))
	.UniqueResultAsync<Customer>();
	// Usage IQueryOver.ListAsync()
	var person = await session.QueryOver<Customer>().ListAsync();
	// Usage IQueryOver.ListAsync<T>()
	var person = await session.QueryOver<Customer>().Select(p => p.Name).ListAsync<string>();
	// Usage IQueryOver.SingleOrDefaultAsync<T>()
	var customer = await session.QueryOver<Customer>().SingleOrDefaultAsync();
	//Usage of ISession.FlushAsync()
	_session.FlushAsync(cancellationToken);
