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#.
