Blazor WebAssembly Overview

Get familiar with the Blazor WebAssembly project structure.

We'll cover the following

There are two types of Blazor applications: Blazor WebAssembly and Blazor Server. Although they share many similarities, they have the following differences:

  • A Blazor WebAssembly application is compiled into WebAssembly and runs directly in the browser.

  • A Blazor Server application is a standard ASP.NET Core application hosted on the server where the web pages interact with the code on the server in real time.

In this lesson, we will get familiar with Blazor WebAssembly.

Introducing Blazor WebAssembly

Blazor WebAssembly is a framework based on .NET that enables developers to create interactive web applications using C#, Razor, and HTML. Unlike traditional web development frameworks that rely heavily on JavaScript for client-side interactions, Blazor WebAssembly allows developers to write front-end code in C#, which is then executed in the browser using WebAssembly.

WebAssembly is a binary instruction format that runs at near-native speed in modern web browsers. Blazor leverages this technology to enable compiled C# code to run in the browser, offering a way to build web applications using languages and tools traditionally associated with server-side development.

This framework provides a familiar programming model for developers who are already well-versed in C# and .NET, allowing them to use their existing skills to build dynamic and interactive web applications. With Blazor WebAssembly, developers can create single-page applications (SPAs) that offer rich interactivity and responsiveness without relying on JavaScript for the client-side logic.
