About

Microsoft ASP.NET Core is an open-source, cross-platform web framework and the successor to ASP.NET that enables development of web apps and APIs using .NET on Windows, macOS, or Linux.

It offers high performance via the Kestrel server, built-in dependency injection, unified MVC and Web API programming, minimal APIs, flexible configuration per environment, and side-by-side versioning.

Blazor is an open-source web framework from Microsoft that allows developers to build full-stack web applications using C# and .NET.

It supports client-side rendering with WebAssembly, server-side rendering with interactive components via SignalR, reusable Razor UI components, hot reload during development, and the ability to share code and libraries between client and server.
