ASP.NET Core – Blazor framework (ASP3)

Programming, .NET

This course teaches developers to build web applications entirely in C# with the Blazor framework inside ASP.NET Core. You avoid client-side JavaScript and stay productive in one language while building a mini application in a hands-on workshop.

During the course you will explore Blazor's runtime and app model, compare Blazor Server and WebAssembly, and learn component design, routing, forms and data access. Key topics include dependency injection, background tasks, identity and modern security.

THIS TRAINING COURSE WILL HELP YOU:

  • Build interactive web apps using the modern Blazor framework
  • Create modern web applications with C# and .NET
  • Understand the .NET platform and use related tools and technologies

WHO SHOULD ATTEND?

  • Web developers who want to learn modern web technologies
  • .NET developers aiming to build modern web apps with Blazor
  • Students studying software development who want Blazor skills
  • Project managers wanting to understand Blazor capabilities and limits
