ASP.NET Core is an open‑source, cross‑platform framework for building modern cloud‑based web applications and services with .NET and C#. It provides a modular, high‑performance stack that includes routing, middleware, MVC, Razor, and API capabilities.

Use cases

build a RESTful API for a web or mobile client
create server‑side rendered web pages using Razor or MVC
develop real‑time web applications with SignalR
host microservices in containers on Linux, Windows, or macOS
build full‑stack web apps with Blazor using C# for both client and server
implement authentication and authorization for enterprise web portals

When to choose

you are already invested in the .NET ecosystem and want to use C# end‑to‑end
you need high performance and low overhead for cloud‑native services
cross‑platform deployment on Windows, Linux, and macOS is required
you want built‑in support for Razor, MVC, and Blazor components
you need tight integration with Azure services and other Microsoft tools

When to avoid

your team prefers JavaScript/TypeScript‑centric stacks like Node.js or Deno
you need a lightweight framework with minimal runtime dependencies outside .NET
the project targets platforms where .NET is not supported (e.g., some embedded systems)
you require a front‑end framework that relies heavily on client‑side JavaScript libraries
