## What it is
MvvmCross is an opinionated cross-platform MVVM framework for the .NET ecosystem, supporting Android, iOS, MacCatalyst, tvOS, macOS, WinUI, and WPF. It provides a customizable data-binding engine, ViewModel-first navigation, dependency injection, and a plugin framework to maximize code sharing across platforms.

## Use cases
- build cross-platform mobile apps with shared viewmodels in .NET
- share business logic between android and ios apps
- implement mvvm pattern in xamarin or maui projects
- navigate between viewmodels without platform-specific code
- bind viewmodels to native views on ios and android
- add dependency injection to a .net mobile app
- extend app capabilities with plugins like location and localization

## When to choose
- you are building native mobile or desktop apps in C#/.NET across multiple platforms
- you want maximum code sharing of viewmodels and business logic with native UIs
- you need a mature, extensible MVVM framework with a large plugin ecosystem

## When to avoid
- you are building a web app or using non-.NET languages
- you prefer a lightweight unopinionated pattern without a framework
- you only target a single platform where platform-native patterns suffice

## Facets
- artifact type: framework
- maturity: stable
- function: mobile-framework, state-management, ui-components, plugin-system
- domain: mobile-development, cross-platform, web-development, desktop-applications
- platform: windows, dotnet, cross-platform
- tags: mvvm, xamarin, data-binding, viewmodel-navigation, wpf, winui, maccatalyst, tvos, c-sharp, dependency-injection, android, ios, macos, mobile, desktop
