What's New in .NET Core 8: Exploring the Features and Enhancements

.NET Core 8 brings a host of improvements and features that enhance performance, developer experience, and support for modern application development. Here's a breakdown of the most exciting updates in .NET Core 8:

1. Improved Performance

.NET 8 focuses heavily on performance with advancements in:

• Code generation and JIT compilation: These updates enable faster application execution by optimizing the code generation process.
• Loop and general optimizations: Enhancements improve runtime efficiency in computationally intensive scenarios.

2. Enhanced JSON Support

• JSON columns in SQLite: Developers can now seamlessly interact with JSON data in SQLite.
• Performance improvements: JSON operations in .NET are faster, allowing for more efficient data handling in APIs and other JSON-intensive applications.

3. New Data Types

• TimeOnly and DateOnly support for SQL Server: These data types allow for precise representation of time and date values without requiring full datetime fields, simplifying use cases like scheduling and logging.

4. Improved Serialization and Deserialization

• Support for required and init properties: Serialization now handles complex object structures better, reducing errors and improving compatibility.

5. Better Memory Efficiency

• Generational Garbage Collection (GC): Enhancements in GC reduce memory usage and improve application responsiveness, particularly for large-scale applications.

6. Optimized Performance for Frameworks

• ASP.NET Core: Significant performance improvements for web applications.
• .NET MAUI: Enhanced runtime and UI performance for cross-platform applications.

7. Extended AI and ML Support

.NET 8 enhances support for artificial intelligence and machine learning tasks with tools for:

• Data analysis
• Predictive modeling
• Automation

8. Tokens for Cookie-Less Clients

A new parameter enables token-based authentication for clients that do not support cookies, improving security and usability in modern application environments.

9. Long-Term Support (LTS)

.NET 8 offers extended support for up to three years, making it an ideal choice for enterprise applications requiring stability and long-term updates.

10. Time Abstraction

• TimeProvider Class and ITimer Interface: These additions make it easier to mock time in test scenarios, streamlining unit testing for time-dependent logic.

Other Noteworthy Features

• Complex Type Object Improvements: Simplifies development with intricate data structures.
• Raw SQL Queries for Unmapped Types: Developers can execute raw SQL queries without the need for predefined mappings.
• Lazy Loading Enhancements: Optimizes entity loading for scenarios with large datasets.
• Bulk Updates and Deletes: Improves database operation efficiency.
• HierarchyId Support: Adds support for working with hierarchical data structures in SQL Server.

Conclusion

.NET Core 8 is a significant step forward for the .NET ecosystem, offering features that improve performance, developer productivity, and support for modern development practices. Whether you're building web applications, APIs, or AI-driven solutions, .NET 8 provides the tools and improvements to make your projects faster, smarter, and more efficient.
