.NET 8 Architecture Overview

What is .NET 8?

.NET 8 is the latest Long-Term Support (LTS) release of the .NET platform. It unifies cloud, desktop, mobile, and web development under a single framework, offering performance improvements, modern language features, and better tooling.

Key Components of .NET 8 Architecture

Common Language Runtime (CLR): Manages code execution, memory, and garbage collection.
Base Class Library (BCL): Provides foundational APIs for collections, I/O, networking, and more.
ASP.NET Core: Framework for building web apps, APIs, and microservices.
Entity Framework Core 8: ORM for data access with support for JSON columns, lazy loading, and raw SQL.
.NET MAUI: Cross-platform UI framework for building mobile and desktop apps.
Blazor: Web UI framework using C# and Razor syntax for client-side and server-side rendering.
Native AOT: Ahead-of-time compilation for faster startup and reduced memory usage.
.NET Aspire: A new cloud-native stack for building distributed, observable applications.

Layered Architecture in .NET 8 Projects

Presentation Layer: UI or API endpoints (e.g., Razor Pages, Blazor, Web API)
Application Layer: Use cases, services, and orchestration logic
Domain Layer: Business logic, entities, value objects, and domain services
Infrastructure Layer: Data access, external APIs, file systems, and messaging

New Features in .NET 8

C# 12: Includes primary constructors, collection expressions, and default lambda parameters
Improved Performance: Faster JSON serialization, better GC, and reduced allocations
Enhanced Minimal APIs: More expressive and easier to test
SignalR Improvements: Better real-time communication support
Globalization Enhancements: New modes for mobile and web apps

Deployment Options

Docker & Kubernetes: Containerized deployment for scalability
Azure App Services: Cloud hosting with CI/CD integration
Native AOT: Compile to native binaries for performance-critical apps

Conclusion

.NET 8 provides a unified, high-performance platform for building modern applications across web, mobile, desktop, and cloud. Its architecture promotes clean separation of concerns, scalability, and maintainability.
