Four Core Ways .NET is Used in Web Development Today
Modern web development with .NET is highly versatile, allowing architects to choose the best pattern for the specific business requirement. Here are the four primary use cases that define how .NET is utilized:
- Building High-Performance Back-End APIs and Microservices: This is arguably the most common and critical use. .NET's high-performance Kestrel web server and its lightweight architecture make it ideal for creating RESTful APIs and gRPC services. These APIs serve as the data backbone for mobile apps, Single Page Applications (SPAs) built with React or Angular, and internal system integrations. For large enterprises, this is the foundation for a scalable Microservices architecture.
- Full-Stack Web Applications (MVC and Razor Pages): For applications where server-side rendering is preferred for SEO, faster initial load times, or simpler development, .NET MVC (Model-View-Controller) and Razor Pages remain excellent choices. They provide a structured, maintainable approach to building traditional web portals, content management systems, and internal business applications.
- Interactive Client-Side UIs with Blazor: Blazor is a game-changer, allowing developers to build interactive, client-side web UIs using C# instead of JavaScript. Blazor WebAssembly runs C# code directly in the browser, while Blazor Server handles the UI via a SignalR connection. This unifies the full-stack language, dramatically reducing cognitive load and accelerating development cycles.
- Real-Time Communication Services (SignalR): .NET SignalR is a library that simplifies adding real-time web functionality to applications. This is essential for features like live chat, instant notifications, real-time dashboards (e.g., stock tickers, logistics tracking), and collaborative tools. It ensures low-latency, high-frequency data updates, which is critical for applications in FinTech and logistics sectors.
