Master Entity Framework in a step-by-step manner and learn advanced querying techniques, migrations, and testing About This Video Explore data validation using attributes and use validation inside MVC controllers Master advanced query techniques Learn how to enhance the performance or scalability of Entity Framework Core Delve into concurrency handling and understand transactions Perform migrations and protect existing data during rename operations In Detail You will start the course by exploring data validation and learn how to implement data validation inside your model using attributes. Then you will use validation inside MVC controllers and expose validations inside your MVC views in the user interface. Next you will delve into advanced query techniques. You will see how asynchronous code helps your applications scale better and explore query performance. Further, you will learn how to protect application data from concurrent access by multiple users, see how transactions enable changes to multiple tables and learn how to create an abstraction layer on top of Entity Framework by using the repository pattern. Next you will embrace migrations and embark on a journey designed to develop the database structure as your application evolves using Entity Framework Core migrations. Then you will create custom migrations that update database schemas and use custom scripts to perform migrations while protecting existing data during rename operations. Finally you will explore testing and set up a further learning path by writing unit and integration tests. You will see how to bring Entity Framework into a project based on an existing database. In conclusion, you will learn about additional areas Entity Framework core can be used in, and what types of data structure (besides RDBMS) can be accessed with EF Core.

Learn how to leverage the features of the new Entity Framework Core APIs and use them to build pure .NET Core applications. About This Book Learn how to effectively manage your database to make it more productive and maintainable. Write simplified queries using LINQ to acquire the desired data easily Raise the abstraction level from data to objects so teams can function independently, resulting in easily maintainable code Who This Book Is For This book is for .NET Core developers who would like to integrate EF Core in their application. Prior knowledge of .NET Core and C# is assumed. What You Will Learn Create databases and perform CRUD operations on them Understand and build relationships (related to entities, keys, and properties) Understand in-built, custom, and remote validation (both client and server side) You will learn to handle concurrency to build responsive applications You will handle transactions and multi-tenancy while also improving performance In Detail Being able to create and maintain data-oriented applications has become crucial in modern programming. This is why Microsoft came up with Entity Framework so architects can optimize storage requirements while also writing efficient and maintainable application code. This book is a comprehensive guide that will show how to utilize the power of the Entity Framework to build efficient .NET Core applications. It not only teaches all the fundamentals of Entity Framework Core but also demonstrates how to use it practically so you can implement it in your software development. The book is divided into three modules. The first module focuses on building entities and relationships. Here you will also learn about different mapping techniques, which will help you choose the one best suited to your application design. Once you have understood the fundamentals of the Entity Framework, you will move on to learn about validation and querying in the second module. It will also teach you how to execute raw SQL queries and extend the Entity Framework to leverage Query Objects using the Query Object Pattern. The final module of the book focuses on performance optimization and managing the security of your application. You will learn to implement failsafe mechanisms using concurrency tokens.
