Mapsui is library for apps that need a map

• Intended to develop apps
• Designed to be fast and responsive (see architecture)
• All data fetching is on a background thread (disk, web, or database)
• Code is written to be used cross platform (using PCL or code sharing)
• Based on a modified version of SharpMap.
• Uses BruTile to access tile services

There are four platforms supported:

• Windows Desktop - WPF on .NET 4.5

• BruTile - Used for the tile layers.

Take a look at the wiki. We are starting to add some information there. If you have a question please submit an issue or a question on stackoverflow the the 'mapsui' tag (I will get a notification).

• There is limited documentation.
• Breaking changes will be introduced frequently. We change the API whenever we feel this is an improvement.
• We adopt new technologies relatively fast, and dropping support for older frameworks.
• Only use this project if you are willing to dig into the code.
• Although there is a general plan of where to go with this library there are not enough resources to go towards that goal in a systematic way. New functionality is driven by what is needed in our projects.
