## What it is
Mapsui is a .NET map component library for embedding interactive maps in applications built with MAUI, Avalonia, Uno Platform, Blazor, WPF, WinUI, Windows Forms, Eto, and .NET Android/iOS. It supports OpenStreetMap and other map data sources across all major .NET UI frameworks.

## Use cases
- display an interactive map in a MAUI app
- add openstreetmap tiles to a WPF application
- embed a map component in a Blazor web app
- show geospatial data on a map in an Avalonia desktop app
- render maps in a cross-platform .NET mobile app
- add map view with markers and layers to WinUI app
- display GIS data in a Windows Forms application

## When to choose
- you are building a .NET app on MAUI, Avalonia, Uno, Blazor, WPF, WinUI, WinForms, Eto, or .NET mobile and need an embedded map
- you want a single map component API that works across multiple .NET UI frameworks
- you need OpenStreetMap or custom tile/layer rendering in .NET

## When to avoid
- you are building with JavaScript/TypeScript frontends like React or Vue (use Leaflet or MapLibre instead)
- you need a full server-side GIS platform rather than a client UI component
- your project is not on the .NET platform
