You won't believe number 7!
I know, the clickbait joke is rather lame, but I can assure you that this session is not! In this session, I'll take you on a journey in some lesser known features of EF Core and how they can benefit your projects.
In the .NET 8 era, EF Core has far surpassed what Entity Framework used to be, and has become an ORM powerhouse with features that are useful in many different scenarios. But unless you are constantly keeping up with the latest evolutions, chances are you are missing some opportunities to improve your EF Core usage in your projects.
And as the audience, you will have a say in some of the content of this session!

Is src available somewhere?

Code first is the worst thing to ever happen in EF. Barely any programmer knows how to design a good database and especially a relational one. EF talks should solely focus on how a database should be designed and not trying to give advanced tricks to solve problems that need a solution at the foundation.
I realise Microsoft has been holding a gun to MVP's heads for years now to only teach people things that will make Azure earn more profit but it's getting ridiculous.
BTW you can do multiple DBSets from different databases in a single DBContext. Not native, you have to write your own extension but it works.
If you need a real fake one Hannes, querying multiple contexts in a single expression is something Microsoft has been forgetting for over 15 years. And that would be the proper way how Microsoft should implement the very basic functionality to query cross-database. Then people wouldn't have to write unsupported hacks to get DBSets from multiple databaes in a single DBContext anymore.

Someone get the speaker to do the presentation in a normal font, not handwritten font

Sql Server - ok, I stopped watching right there. Some normal db maybe?

[@Grrbrr404]

Not sure about Hierarchical Ids, but everything else can be used with other database as well. Using postgres myself, so I have first hand experience

[@msdevel]

You're a junior developer, right? Such a childish, thoughtless, and unproven opinion.
