Blazor is an ASP.NET component designed for creating dynamic web user interfaces using C# rather than JavaScript. With Blazor, developers can run genuine .NET code directly in the browser through WebAssembly technology. The .NET platform encompasses a wide array of tools, programming languages, and libraries that facilitate the development of various application types. ASP.NET is equipped with support for widely accepted authentication standards. Its integrated features enhance the security of applications against threats like cross-site scripting (XSS) and cross-site request forgery (CSRF). Moreover, ASP.NET includes a pre-configured user database that accommodates multi-factor authentication and integrates with external authentication services such as Google and Twitter, enabling a seamless user experience. This robust framework ensures that developers can build secure and interactive applications efficiently.
