.NET 9 is Out Now

The latest releases in the .NET ecosystem continue to push boundaries, enhancing performance, security, and developer productivity. Here’s a detailed look at the exciting updates across C# 13, ASP.NET Core, Entity Framework (EF) Core, .NET Runtime, Libraries, SDK, and .NET MAUI.

πŸš€ C# 13. Simplifies coding like never before

C# 13 adds tools to help developing clean and efficient code easier:

  • Params Collections: Declare parameters as collections to improve code readability in methods with variable arguments.
  • Enhanced Lock Types: Increase thread safety choices while lowering complexity in multithreaded programming.
  • New Escape Character: The new escape character is more versatile, making string manipulation easier.
  • Implicit Index Access: simplifies initialization by providing simple access to elements in a collection or array.

🌐 ASP.NET Core. Better Performance and Robust Security

ASP.NET Core sees significant improvements, particularly in performance and security:

  • OpenAPI Enhancements: Improved integration and tooling make API documentation seamless and efficient.
  • Faster Asset Delivery: Optimizations in static file handling and compression improve load times.
  • Private Access Request (PAR) Support: Enhanced security for confidential client flows in OAuth 2.0.
  • HybridCache Library: Combines in-memory and distributed caching for better performance and scalability.

πŸ—„ EF Core. Next-Level Data Management

EF Core delivers powerful tools for faster and more flexible database interactions:

  • Improved Cosmos DB Support: Enhanced querying capabilities for applications using Azure Cosmos DB.
  • Pre-Compiled AOT Queries: Native Ahead-of-Time query compilation for faster execution.
  • Enhanced LINQ: Optimizations make LINQ queries more efficient and expressive.
  • Streamlined Migrations: Simplifies database schema evolution with better tooling and APIs.

These features help developers build robust, scalable data access layers with ease.

βš™ Runtime. Smarter and Faster Applications

The .NET Runtime focuses on adaptability and performance with several key updates:

  • Feature Switches: Dynamically toggle runtime features based on app needs.
  • Control-Flow Enforcement: Strengthens security by preventing runtime exploits.
  • Dynamic Adaptation: Automatically adjusts performance for different app sizes and workloads.

πŸ“š Libraries. Enhanced Flexibility and Security

New updates to the .NET libraries offer expanded functionality:

  • Base64Url: Efficient encoding for web-safe Base64 operations.
  • TimeSpan Overloads: Simplified operations involving time intervals.
  • New Collection Types: Increased flexibility for data manipulation.
  • Cryptography Upgrades: Improved algorithms and APIs for secure applications.

🧰 SDK. Boosting Developer Productivity

The .NET SDK introduces tools to make development faster and more intuitive:

  • Parallel Test Execution: Speeds up testing, reducing build times.
  • New Terminal Logger: Default logging in CLI with clearer and more concise output.
  • Workload Sets: Easily manage related workloads for streamlined development.
  • More Analyzers: Improved code quality with advanced static analysis tools.

πŸ›  .NET Aspire. Smarter Build and Telemetry Tools

.NET Aspire offers smarter tooling for modern development:

  • New MSBuild SDK: Improved build pipeline with faster compilation and better error reporting.
  • Improved Dashboard: Comprehensive insights into project metrics.
  • Telemetry Enhancements: Better instrumentation for understanding application behavior.
  • Dependency Wait Support: Easily manage initialization dependencies for smoother app startups.

These updates empower developers to monitor and optimize projects effectively.

πŸ“± .NET MAUI. Lightweight and Efficient Mobile Apps

.NET MAUI brings significant upgrades for cross-platform mobile app development:

  • Native AOT Deployment: Smaller, faster apps with Ahead-of-Time compilation.
  • API Embedding: Embed APIs into apps for deeper integration.
  • Full Trimming: Eliminate unused code for optimized app size.
  • New Controls: Add more interactive elements with updated UI controls.

These enhancements ensure that .NET MAUI continues to lead in cross-platform mobile development.
