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.

"Na výuce se mi líbilo, že vhodně kombinuje teoretickou část s praktickými cvičeními. Pan školitel umí vysvětlovat poutavou formou a velmi ochotně poradí, případně vysvětlí cokoli, co je zapotřebí. Občerstvení na místě je také vynikající. Kurzu nemám co vytknout :-)."
