C# Q & A


What is Blazor in C#?

Blazor is a modern web framework for building interactive and dynamic web applications using C# and .NET technologies. Developed by Microsoft, Blazor allows developers to create single-page applications (SPAs) and web applications entirely in C#, eliminating the need for JavaScript for client-side logic. It offers two main hosting models: Blazor WebAssembly and Blazor Server.


  1. Blazor WebAssembly: With this model, the entire Blazor application runs directly in the user’s web browser using WebAssembly. It enables the creation of client-side web applications that can work offline, making it suitable for Progressive Web Apps (PWAs). Developers write C# code, which is compiled to WebAssembly and executed in the browser.


  1. Blazor Server: In this model, the Blazor application runs on the server, and the UI updates are sent to the client over a SignalR connection in real-time. This approach provides a responsive and interactive user experience while keeping most of the application logic on the server. Blazor Server is particularly useful for applications where real-time features are required.


Key features and concepts of Blazor include:


   – Component-Based Architecture: Blazor applications are structured as a hierarchy of reusable components, similar to React or Angular. Each component encapsulates UI and behavior, making it easy to build complex applications.


   – Razor Syntax: Blazor uses Razor syntax, a combination of HTML and C#, for building component templates. This makes it familiar to developers who have worked with ASP.NET Core.


   – Data Binding: Blazor supports two-way data binding, allowing components to interact with data and UI elements seamlessly.


   – Dependency Injection: You can use the built-in dependency injection system to manage services and dependencies within your Blazor application.


   – Routing: Blazor provides routing capabilities for creating multi-page applications or navigating between different views.


   – Authentication and Authorization: Blazor offers built-in authentication and authorization support, making it easy to secure your applications.


   – Interoperability: While Blazor encourages the use of C# for client-side logic, it also supports JavaScript interop for scenarios where JavaScript libraries or APIs are needed.


Blazor simplifies web development by enabling developers to leverage their C# skills for building modern web applications. It combines the power of .NET with the flexibility of web development, making it a versatile choice for a wide range of web projects. Whether you’re building a SPA, a full-stack web application, or integrating web components into an existing .NET application, Blazor provides a robust framework for your web development needs.
