Web Application Development with Blazor: No More JavaScript

This Blazor course shows web developers how to use Blazor and C# to create interactive single-page and multi-page applications with code that, while taking advantage of the complete .NET framework, can run in the browser to fully integrate both client-side and server-side logic. Blazor simplifies the .NET developer’s toolbox by replacing JavaScript when creating interactive web pages (including calling HTML5 APIs like geolocation and local storage). Blazor provides developers with a higher level of integration between client and server-side development, allowing the developer to decide what is the optimal place in the application’s architecture to put any functionality. This Blazor course also shows how to integrate both JavaScript and Blazor to take advantage of the two development paradigms and to extend existing JavaScript pages with Blazor.

Key Features of this Web Application Development with Blazor Training:

  • After-course instructor coaching benefit
  • End-of-course exam included
  • After-course computing sandbox included


This course applied to building application with ASP.NET Core.

What is Blazor?

It is a UI framework that was built to simplify the task of building fast single-page apps that will run on any browser. Blazor is now an alternative to using JavaScript for the same purposes.
