Reviews

Blazor Server is a .NET web technology for hosting applications that appear to be traditional single-page applications (SPAs), but actually run on the server, enabling traditional Microsoft authentication/authorization schemes. Users get the SPA experience, while developers avoid writing JavaScript and focus on traditional server-side C# implementation.

In this Comprehensive Blazor Server training course, attendees learn how to use C# programming to build UI apps that leverage the same component-based patterns popularized by libraries such as Angular and React. Students learn how to reduce dependence on JavaScript UI libraries and frameworks, using JavaScript only when needed and not as the primary basis of their client-side applications. In addition, attendees learn how to consume data sources and perform authentication and authorization.
