Summary
- Blazor enables building interactive web apps using C# and .NET instead of JavaScript.
- Runs in browsers via WebAssembly, eliminating plugins and ensuring cross-platform compatibility.
- Supports reusable components, routing, and dependency injection for scalable apps.
- Allows code sharing between client and server, improving efficiency.
- Backed by strong tooling like Visual Studio for faster development.
- Ideal for building secure, high-performance, and modern single-page applications.
What is Blazor?
Blazor app builder is basically a single-page app framework where developers can build interactive client-side Web applications with .NET. It uses open web standards sans the plugins or code transpilation. Blazor functions well in all modern web browsers, including mobile browsers.
Microsoft released the Blazor as a new experimental .NET web framework combining the power of C#/Razor and HTML that runs in the browser with WebAssembly.
Here is why Blazor will continue to grow
- Blazor runs in a memory safe sandboxed environment and is as fast as native applications.
- Required SPA features are easily supported by Blazor like components, routing, dependency injection for an up to date experience as a programmer.
- You can deploy Blazor applications on machines having no .NET, just as static files.
- Blazor comes with ultra-rich IntelliSense and tooling for lesser development time.
- It is supported by all mainstream browsers like Chrome, Edge, Firefox, Opera, Safari along with the ability to run on older (non-WebAssembly) ones via asm.js.
As a developer, you program the code in C# in the case of JavaScript, and you use most of the .NET ecosystem of open source libraries. For the majority of the part, if it is a .NET Standard, it will function in the browser.
The code of .NET runs inside the context of WebAssembly. In this case, what you are doing is, running a ‘.NET’ inside your browser on the client-side with no use of plugins, no Silverlight, Java, Flash, but just the open web standards.
Key benefits of using Blazor
Interactive web UI
With Blazor, you can develop interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components with C#, HTML, and CSS. With client and server code written in C#, it is easy to share code and libraries.
Open web standards
Blazor uses open web standards without plug-ins or code transpilation. Blazor works in all modern web browsers, including mobile browsers.
Share code and libraries
Blazor apps can use existing .NET libraries. .NET Standard provides the same code and libraries for the server, in the browser, or anywhere you write .NET code.
Free Tools
Visual Studio and Visual Studio Code together give a great Blazor development experience on Windows, Linux, and macOS.
UI Component Ecosystem
Re-usable UI components from vendors like Telerik, DevExpress, Syncfusion, Radzen, Infragistics, GrapeCity, jQWidgets, and others.
