blazor tutorials

What is Blazor?

The ASP.NET Team has created a new set of tooling called Blazor. It is a framework for client-side applications written in .NET, running under WebAssembly.

  • It is based on existing web technologies like HTML and CSS, but you use C# and Razor syntax instead of JavaScript to build composable web UI.
  • It gives all the benefits of a rich, modern single-page application (SPA) platform while using .NET end-to-end.
  • The idea about Blazor is to be able to combine Razor and C# into a client-side web project that runs completely in the browser.


WebAssembly is a binary format for the code in the browser, and it runs much faster than traditional JavaScript. It gives the browser several advantages, such as:

  • Runs at near-native performance
  • Runs in a memory-safe, sandbox
  • It compiles from a range of languages, i.e., .NET, C, C++, Java, Rust, etc.

The main advantage of WebAssembly is that it handles memory-rich jobs and multi-threading very well as compared to javascript.


Blazor contains all the features of a modern web framework such as:

  • A component model for building composable UI
  • Routing
  • Layouts
  • Forms and validation
  • Dependency injection
  • Live reloading in the browser during development
  • Server-side rendering
  • Full .NET debugging both in browsers and in the IDE
  • Rich IntelliSense and tooling
  • Publishing and app size trimming
