Mastering Entity Framework Core with .NET 5 Practice Exam
About Mastering Entity Framework Core with .NET 5 Exam
This exam is designed to assess the knowledge and proficiency of candidates in using Entity Framework (EF) Core with .NET 5 for building robust, scalable, and efficient data-driven applications. Candidates will be tested on their ability to integrate EF Core within .NET 5 applications, optimize data queries, implement CRUD operations, and manage database schema migrations. The exam will cover various EF Core features, including working with models, relationships, LINQ queries, and data validation. Candidates should have a basic understanding of C# programming, relational databases, and data-driven application development, and should be comfortable with foundational .NET development practices.
Skills Required
- Familiarity with .NET 5 core concepts such as application structure, dependency injection, and middleware.
- Deep understanding of EF Core and its features such as DbContext, DbSet, LINQ queries, and querying data.
- Ability to create and manage database models, relationships, and use data annotations for validation.
- Proficiency in implementing create, read, update, and delete operations using EF Core.
- Knowledge of EF Core migrations, handling schema changes, and managing database versioning.
- Understanding query optimization techniques using lazy loading, eager loading, and explicit loading.
- Ability to implement optimistic concurrency control and transaction management in EF Core.
- Skills in identifying and optimizing slow queries, improving database performance using indexing and query modifications.
Who should take the Exam?
This exam is ideal for .NET developers, software engineers, and application developers who are working with EF Core to build and maintain database-driven applications. It is also suitable for those transitioning from traditional ADO.NET or other ORMs to EF Core for database management in modern .NET 5 applications. This exam is also beneficial for professionals seeking to validate their expertise in using EF Core for efficient and effective data management in .NET 5 applications, whether they are building enterprise-level solutions, web applications, or microservices.
