Practical Entity Framework Core 6

Take a developer journey that paves the way to enterprise-level database access from .NET and C# using the object-relational mapper (ORM) of choice. This second edition is revised to cover Entity Framework Core 5 and 6 (EF) and includes new content on table-per-type mapping, LINQ improvements (filtered includes), many-to-many navigation changes, split queries, simple logging using the DBCommandInterceptor, and other improvements available in EF Core 6. Real-world examples and considerations are presented in this book to help you create robust and efficient database solutions. Throughout the text, actual problems, questions, and common pitfalls are provided to help you recognize optimal solutions for maximum success in the different application scenarios you might encounter.

Practical Entity Framework Core 6 focuses on the code first approach to developing a database. Taking the code first approach allows the entire database to be built and maintained in code using EF Core 6 so there is never a situation in which you cannot restore the database schema. Additionally, the code first approach creates an entirely transparent record of changes to the database that is easily tracked in source control systems such as GitHub. Emphasis throughout the book is on leaving you well positioned to architect and lead data development efforts for your organization.

What You Will Learn

• Build robust and maintainable databases using a code first approach
• Create and execute stored procedures, triggers, and functions
• Analyze and optimize performance of database queries
• Ensure data integrity through keys, constraints, and relationships
• Encrypt your database columns at rest with TDE and Always-On Encryption
• Leverage the FluentAPI and attributes for entity configuration
  
  Who This Book Is For
  .NET developers who work with enterprise-level applications and need to interact with data structures and data within the back end data store, developers who want to take a code first approach to building database applications to prevent conflicts and optimize efficiency, and those who are moving into full-stack roles, or into senior and architectural roles, and will be responsible for database design and implementation

Gives you a solid understanding of critical entity framework components and operations Provides examples of best practices for scalable and maintainable applications Teaches you how to optimize efficiency to provide better overall user experiences
