Course Overview

Blazor is a client-side UI framework used to develop rich web UI experiences using HTML, CSS, and C# instead of JavaScript. Blazor is similar to other JavaScript frameworks but uses WebAssembly to execute C# code in the browser so that the front- and back-end of the web application can be written in the same language.

This Progressive Web Application Development using Entity Framework Core and Blazor training course teaches attendees how to create modern Progressive Web Applications (PWAs) using Blazor. Students learn how to use PWA to create an app-like experience in a website that acts and feels like a native desktop/mobile app.

Key Learning Areas

  • Install and use the Entity Framework package to work with databases on the server-side
  • Install packages required to develop the client-side Blazor applications
  • Use components, services, dependency injection, layout, and routing
  • Enable PWA features in an application by creating service workers
  • Use PWA features, such as push notifications and storage with IndexedDB
