By utilizing WebAssembly, Blazor can execute C# code directly in the browser, making it possible to build rich, interactive applications without relying on JavaScript frameworks.
Here are five important things you need to know about Blazor:
1. Blazor supports two hosting models: server-side and client-side. In the server-side model, the application logic runs on the server and communicates with the client using SignalR, a real-time communication library. The client-side model, on the other hand, enables the application to run entirely in the browser by downloading the necessary .NET runtime and executing the code locally. Both models have their advantages and choosing between them depends on factors such as performance requirements, network conditions, and the need for offline support.
2. Blazor’s component-based architecture allows developers to build reusable UI elements called components. Components are self-contained, encapsulated units of functionality that can be composed together to create complex user interfaces. Components can have properties, event callbacks, and lifecycle methods similar to popular JavaScript frameworks like React or Angular. Blazor components can be easily shared and distributed as libraries, fostering code reuse and modularity.
3. Blazor provides a rich set of built-in UI controls and libraries for common web development tasks. These include form controls, layout components, navigation components, and more. Blazor also supports third-party component libraries such as Telerik UI for Blazor and Syncfusion Blazor Components, which offer a wide range of pre-built UI elements and functionalities. These libraries empower developers to create professional-looking web applications with ease.
4. Blazor benefits from the extensive ecosystem and tooling of the .NET ecosystem. Developers can leverage their existing knowledge of C# and .NET frameworks to build Blazor applications, reducing the learning curve and increasing productivity. Blazor projects can be seamlessly integrated with popular development tools such as Visual Studio and Visual Studio Code, providing features like IntelliSense, debugging, and code refactoring. Additionally, Blazor benefits from the vast collection of NuGet packages available in the .NET ecosystem, enabling developers to leverage existing libraries and utilities.
5. Blazor’s server-side hosting model provides several advantages over traditional JavaScript frameworks. Since the application logic runs on the server, it can benefit from the scalability, reliability, and security features of server-side technologies. Server-side Blazor applications can handle complex business logic and data processing on the server, reducing the burden on the client’s resources. This model also provides a familiar programming model for developers accustomed to server-side development, making it easier to transition from traditional web development to Blazor.

Blazor, Blazor, Blazor. The name itself evokes curiosity and excitement in the web development community. It represents a paradigm shift in the way web applications are built, empowering developers to write frontend code using C# instead of JavaScript. By utilizing WebAssembly, a low-level bytecode format supported by all modern browsers, Blazor enables the execution of .NET code directly in the browser. This eliminates the need for JavaScript interop and opens up a world of possibilities for developers who prefer C# as their primary programming language.
Blazor provides developers with multiple hosting models to choose from, depending on their specific requirements. The first hosting model is called Blazor Server, where the application’s logic and user interface are executed on the server. In this model, the browser acts as a thin client, sending UI events to the server and receiving UI updates in response. This approach offers a high level of interactivity and real-time communication but requires a persistent connection between the client and server.
The second hosting model is known as Blazor WebAssembly. With this model, the entire Blazor application is downloaded to the client’s browser as WebAssembly bytecode. The application then runs directly in the browser, leveraging the browser’s JavaScript engine for execution. Blazor WebAssembly provides a fully client-side experience, where the UI and logic are executed on the client device. This hosting model offers offline support, faster loading times, and the ability to run in environments without a constant network connection.
Blazor components lie at the heart of Blazor applications. These reusable UI elements encapsulate both the UI markup and the associated logic in a single C# class. Components can be composed hierarchically to build complex user interfaces, and they can communicate with each other through parameters and events. Blazor components resemble other component-based frameworks like React or Angular, but with the added advantage of using C# for both the UI and logic. This unified approach simplifies development and maintenance, as developers can leverage their existing knowledge of C# and the .NET ecosystem.
Blazor leverages the Razor syntax, a markup syntax that allows developers to seamlessly integrate C# code into HTML templates. This enables the creation of dynamic and data-bound UIs, where C# code can be used to generate HTML elements, apply conditional rendering, or iterate over collections. Razor syntax is intuitive and familiar to developers who have worked with other templating languages, making it easy to get started with Blazor.
One of the key benefits of Blazor is its seamless integration with the .NET ecosystem. Developers can leverage the vast array of libraries, frameworks, and tools available in the .NET ecosystem to enhance their Blazor applications. Whether it’s using popular libraries like Entity Framework for data access, integrating with authentication providers like Azure Active Directory, or using third-party UI component libraries, developers can tap into the rich .NET ecosystem to accelerate their development process.
Blazor’s tight integration with the .NET ecosystem also brings the advantages of a statically typed language to web development. C# provides strong typing, compile-time checks, and powerful tooling, enabling developers to catch errors early in the development process. This reduces the likelihood of runtime errors and improves the overall robustness and maintainability of Blazor applications.
Blazor’s performance is another noteworthy aspect that sets it apart from traditional JavaScript-based frameworks. By leveraging WebAssembly, Blazor achieves near-native performance, as the code is compiled to a low-level bytecode that can be executed efficiently by the browser. This results in faster load times, smoother animations, and improved overall responsiveness of the application.
Blazor also incorporates a feature called “Ahead-of-Time” (AOT) compilation, which further enhances performance. With AOT compilation, the Blazor application can be precompiled into WebAssembly bytecode during the build process, eliminating the need for just-in-time (JIT) compilation in the browser. This reduces startup time and eliminates any performance overhead associated with JIT compilation, resulting in snappier and more efficient applications.
Another key advantage of Blazor is its ability to enable code sharing between the frontend and backend of an application. With Blazor, developers can write shared code libraries that can be utilized by both the client-side Blazor application and server-side .NET components. This eliminates the need for duplicating logic and reduces the potential for inconsistencies between the frontend and backend codebases. It also allows for seamless integration with existing .NET applications, enabling developers to leverage their existing codebase and infrastructure.
Blazor also provides a rich set of features for handling user input, form validation, and data binding. Developers can easily bind UI elements to data models, making it effortless to keep the UI in sync with the underlying data. Blazor supports both one-way and two-way data binding, allowing for real-time updates as data changes. Additionally, Blazor includes built-in validation mechanisms that can be applied to form inputs, ensuring data integrity and providing a smooth user experience.
Security is a top priority in web development, and Blazor offers robust security features to protect applications from common threats. By leveraging the .NET runtime, Blazor benefits from the security features provided by the runtime environment, such as memory management, type safety, and exception handling. Additionally, Blazor incorporates built-in features for protecting against cross-site scripting (XSS) attacks, request forgery, and other common web vulnerabilities. With its strong integration with the .NET ecosystem, developers can also utilize established security frameworks and practices to further enhance the security of their Blazor applications.
Blazor’s extensibility is another notable aspect that makes it a powerful framework.
