The WinUI 3 demo app, WinAppTest, is now decoupled from my hosting/dependency injection libraries.
You can find the latest NuGet packages here:
| Library | NuGet |
|---|---|
| J4JMapLibrary |  |
| J4JMapWinLibrary |  |
This repository contains assemblies for interacting with various online map services and displaying imagery obtained from them:
- J4JMapLibrary is the core library. You can find its documentation here.
- J4JMapWinLibrary contains the actual map control. You can find its documentation here.
- MapLibTests contains XUnit tests for J4JMapLibrary
- WinAppTest contains a demo WinUI 3 app (which is also used for testing)
All the mapping services currently supported by J4JMapControl require authentication. That isn't hard or expensive to obtain, but without credentials no map imagery will be displayed. You can, however, "obtain" credentials for Open Street Maps and Open Topo Maps by supplying a user agent string identifying your app (or the WinAppTest, when you run it on your system).
| Projection | Obtaining Credentials | Links |
|---|---|---|
| Bing Maps | You have to create an account with the service | https://www.microsoft.com/en-us/maps/create-a-bing-maps-key |
| Google Maps | You have to create an account with the service | https://developers.google.com/maps/documentation/maps-static/get-api-key |
| Open Street Maps | You must identify your app with a user agent string | https://operations.osmfoundation.org/policies/tiles/ |
| Open Topo Maps | You must identify your app with a user agent string | https://operations.osmfoundation.org/policies/tiles/ |
Enjoy!
