We begin with an introduction to Entity Framework Core, followed by an essential update on .NET 8, setting the stage for the detailed exploration that follows. The course systematically guides you through the Environment Setup, ensuring you have the necessary tools and understanding to proceed. Begin with basic concepts and progressively advance to more complex topics. The course covers project setup in both Visual Studio and Visual Studio Code, explaining data models, database context, and database support in EF Core. You'll learn about code-first development, migrations, and even reverse engineering an existing database, providing a well-rounded understanding of database interactions using EF Core. Then we delve into querying a database, discussing everything from basics and filters to advanced querying techniques and performance enhancement tips. You'll gain insights into manipulating data, handling changes, and managing database migrations effectively. Next, we will take a deep dive into database relationships, and you'll explore various types of relationships and their practical implementation. As you'll work with raw SQL, views, stored procedures, and the integration of EF Core with ASP.NET Core. The course concludes with a look at data validation, database transactions, and handling data concurrency issues.
