## What it is
ASP.NET Core is the open-source, cross-platform web framework for .NET, used to build modern cloud-based web applications, APIs, IoT apps, and mobile backends. It runs on Windows, Mac, and Linux and consists of modular components with minimal overhead.

## Use cases
- build a rest api in c#
- create a web application on linux with .net
- build a mobile app backend
- host a real-time app with websockets
- develop cloud-native web services
- build an iot backend service

## When to choose
- you are building web apps or APIs in the .NET ecosystem
- you need cross-platform deployment on Windows, Mac, or Linux
- you want a mature, well-supported framework backed by Microsoft and the .NET Foundation

## When to avoid
- your team does not use C# or .NET
- you need a lightweight micro-framework for a tiny service
- you are building a frontend-only static site

## Facets
- artifact type: framework
- maturity: stable
- function: web-framework, http-server, routing, middleware, auth, websocket, api-framework
- domain: web-development, backend, apis, cross-platform
- platform: windows, cross-platform, dotnet
- tags: aspnetcore, csharp, microsoft, cloud, web-apps, iot, mobile-backends, macos, linux
