Introduction to Blazor WebAssembly

3 Ratings

Course Number: ASPNC-110

Duration: 3 days (19.5 hours)

Format: Live, hands-on

Blazor Training Overview

Blazor is a hot new .NET Core web technology for hosting applications that can run your client-side C# code directly in the browser using WebAssembly.

In this Introduction to Blazor WebAssembly training course, attendees learn how to build UI apps leveraging the same component-based patterns popularized by libraries such as Angular and React, but using C# programming. Students learn how to reduce dependence on JavaScript UI libraries and frameworks and utilize JavaScript only when needed, not as the basis of their client-side applications. This course also utilizes an ASP.NET Core backend.
