Entity Framework (EF) Core is an adaptable, lightweight, and open-source iteration of the popular Entity Framework data access technology that functions across various platforms. It enables .NET developers to engage with databases using .NET objects, which significantly diminishes the volume of data-access code that developers usually need to produce. In EF Core, data interactions take place through a model composed of entity classes and a context object that serves as the bridge to the database. This context object supports both querying and data manipulation tasks. Developers have the option to create a model from an existing database or to manually design one that aligns with the database schema. Once the model is established, EF migrations can be used to construct a database from it, ensuring that the database can progress in sync with any modifications made to the model. Additionally, developers can retrieve instances of entity classes from the database using Language Integrated Query (LINQ), allowing for operations such as creating, deleting, and updating records to be executed smoothly through these instances, thereby enhancing the overall data management experience. Ultimately, EF Core not only eases database interactions but also boosts the productivity of data-driven applications, making it a valuable tool for developers. As such, its ability to streamline development processes is a significant advantage in modern software development.
