In Defense of Lazy Loading

I don’t know how this happened but for the last couple years (at least), whenever I read an author who writes about ORMs, I often see a sentiment like this: “ORMs are fine, just make sure you disable this pesky feature called Lazy Loading”.

It’s like this feature is not even needed and only brings confusion and performance issues to everyone who chooses to use it. Well, as you may guess from the title of this article, I disagree with this point of view completely. 

EF Core vs NHibernate – 3.5 : 6.8.

The EF Core team is putting a lot of effort, and EF Core is slowly approaching parity with NHibernate. But it’s still lights years behind, and I don’t even mention all other, non-DDD related features. 

This release arguably makes NHibernate the most advanced ORM in .NET functionality-wise. 

NHibernate has gained two new target frameworks: .Net Core 2.0 and .Net Standard 2.0.  

** Highlights
* IO bound methods have gained an async counterpart. Not intended for parallelism, make sure to await each
call before further interacting with a session and its queries.
* Strongly typed DML operation (insert/update/delete) are now available as Linq extensions on queryables.
* Entities collections can be queried with .AsQueryable() Linq extension without being fully loaded.
* Reference documentation has been curated and completed, notably with a Linq section.
