Entity Framework Training and Certification in Kraków, Poland

Entity Framework training teaches developers how to work with Object-Relational Mapping (ORM) in .NET, enabling seamless interaction between applications and databases. Participants learn how to model and map data from relational databases to C# objects, simplifying database operations. The course covers key concepts such as LINQ queries, migrations, and data validation to efficiently manage data in a database. Advanced topics include optimizing performance, managing relationships between entities, and handling concurrency in multi-user environments. By the end of the training, learners will be able to leverage Entity Framework to build scalable, data-driven applications with ease.
