In Entity Framework Core, the approach to handle ________ is different and more efficient than in Entity Framework 6.
- Change tracking
- Connection pooling
- Database transactions
- Lazy loading
Change tracking in Entity Framework Core has been optimized for better performance compared to Entity Framework 6. It employs various strategies such as change tracking proxies and snapshot-based change tracking to improve efficiency.
________ is a feature in Entity Framework Core that was not available in Entity Framework 6, allowing for better performance optimization.
- Connection pooling
- Lazy loading
- Migrations
- Query caching
Lazy loading in Entity Framework Core enables on-demand loading of related entities, reducing the initial load time of entities and improving performance. This feature was not available in Entity Framework 6, making Entity Framework Core more efficient in certain scenarios.
Which version of Entity Framework introduced support for cross-platform development?
- Entity Framework 4
- Entity Framework 5
- Entity Framework 6
- Entity Framework Core
Entity Framework Core (EF Core) introduced support for cross-platform development, enabling developers to build applications that can run on various platforms, including Windows, macOS, and Linux.
Which version of Entity Framework allows for a more modular approach when adding functionality via NuGet packages?
- Entity Framework 4
- Entity Framework 5
- Entity Framework 6
- Entity Framework Core
Entity Framework Core introduced a more modular approach, allowing developers to add functionality via NuGet packages more easily. This modularity enhances the flexibility and maintainability of the application by enabling the use of only required features, reducing the overall footprint of the application.
In terms of advanced querying capabilities, which Entity Framework version provides better support for LINQ queries?
- Entity Framework 4
- Entity Framework 5
- Entity Framework 6
- Entity Framework Core
Entity Framework Core provides better support for LINQ queries compared to its predecessors. With enhancements and optimizations in query translation and execution, Entity Framework Core offers improved performance and flexibility, making it the preferred choice for advanced querying tasks.
Which version of Entity Framework introduced a more lightweight and extensible architecture?
- Entity Framework 4
- Entity Framework 5
- Entity Framework 6
- Entity Framework Core
Entity Framework Core introduced a more lightweight and extensible architecture compared to previous versions. Its modular design and reduced dependencies make it suitable for a wide range of applications, including those targeting cross-platform and cloud environments. This architecture enables better performance and scalability.
When considering the support for asynchronous programming, which version of Entity Framework offers more advanced features?
- Entity Framework 4
- Entity Framework 5
- Entity Framework 6
- Entity Framework Core
Entity Framework Core provides more advanced features for asynchronous programming compared to Entity Framework 6. It introduces asynchronous query execution, asynchronous SaveChanges, and asynchronous database commands, making it more efficient and scalable in scenarios requiring asynchronous operations.
Entity Framework Core introduced significant changes in the way ________ configurations are handled compared to Entity Framework 6.
- Code-first conventions
- Data annotations
- Fluent API
- XML configuration
Fluent API is a programmatic way to configure database mappings and relationships in Entity Framework Core. It provides more flexibility and control over the configuration compared to Data annotations or XML configuration. This makes it the preferred approach for handling configurations in Entity Framework Core.
The ________ feature in Entity Framework Core offers a more advanced and flexible solution compared to Entity Framework 6.
- Change Tracking
- Code-First Approach
- Query Compilation
- Reverse Engineering
Entity Framework Core introduces the Code-First approach, allowing developers to define the model using code rather than through a visual designer. This offers greater flexibility and advanced capabilities in defining and customizing the database model.
Entity Framework Core has a different implementation of ________ compared to Entity Framework 6, which impacts performance and scalability.
- Eager Loading
- Explicit Loading
- Implicit Loading
- Lazy Loading
Entity Framework Core handles data loading differently, particularly in how it performs eager loading, lazy loading, and explicit loading. Understanding these differences is crucial for optimizing performance and scalability in applications.
