Learn how to use Entity Framework Core in your .NET applications
Entity Framework (EF) Core is a lightweight, extensible, open source and cross-platform object-relational mapper or ORM which enables .NET developers to work with a database using .NET objects and eliminates the need for most of the data-access code that typically needs to be written. Alongside Dapper, it is one of the two most popular ORMs in .NET, and given how much its performance has been improved in the last few .NET versions, it is an excellent choice for any .NET application. In this 8-and-a-half-hour-long course, Hannes Lowette will cover everything you need to know about Entity Framework Core, from its most basic concepts to its most advanced ones, including testing and different database providers. This course is effectively two courses bundled as one, and it is the best resource you could have to learn Entity Framework code in .NET with C#.

Hannes Lowette
With 20 years in .NET development, Hannes has always been passionate about performance, databases, distributed systems and large-scale applications. When it comes to architecture, his opinions have become a bit more nuanced, and the "it depends" card, however boring, gets played in many technical discussions. Hannes has always had a passion for sharing knowledge. It doesn't matter whether it is one-to-one while pair programming, on a conference stage giving a talk or when he's helping people succeed in their careers as a coach. In his free time, when he's not building LEGO® castles with his three kids, he likes to stream his guitar building on Twitch and spends too much time playing online chess and doing all-around geeky stuff. You can always lure him into a chat over a glass of great Whisky.
