This comprehensive course on Entity Framework is designed for both beginner and intermediate-level developers who want to learn how to effectively work with data in their .NET applications. You will start with the basics, including what Entity Framework is, its history, and its advantages. From there, you will dive into creating models, working with data contexts, and querying data with LINQ. You will also learn how to save data, perform CRUD operations, manage relationships and navigation properties, and handle concurrency. Best practices for working with Entity Framework will be covered, including managing performance and scalability, handling errors and exceptions, and creating reusable and testable code. By the end of this course, you will have a solid understanding of Entity Framework and be able to use it to efficiently and effectively manage data in your .NET applications.
