Summary

We have released the Map view on MAUI .net7, unfortunately there was no Windows handler since WinUI doesn’t have a MapControl yet, this proposal closes the gap on Windows by providing a Map handler based on WebView and the Bing Maps SDK. This was discussed internally on the .NET MAUI team, and decided to provide this on the Toolkit and to on MAUI itself.

Motivation

Enabling users to have a cross platform implementation of Maps

Detailed Design

Using a WebView2 control to load a local HTML page that renders the Bing Maps control, and add javascript interop to map MAUI Map properties to the Web Bing maps control.

Usage Syntax

XAML Usage

None

C# Usage

 MauiApp.CreateBuilder().UseMauiCommunityToolkitMaps("key")

Drawbacks

The drawback is this will be removed in the future when WinUI team provides the MapControl.

@VladislavAntonyuk this would live in the Community Toolkit until we have a proper solution for WinUI , and then we would obsolete and drop it from the Community Toolkit. We talked internally and this was the best decision as we don’t want to put it on MAUI repo for now. This would be shipped on the toolkit on a 7.0 version.

What performance issue? tbh I run the sample and I don’t see any big performance issues compared with other platforms. Also the implementation uses device capabilities like gps to get user location etc. |

@jfversluis @brminnick can someone help me figure if this can go in our not? who makes the decision? if it can’t be here I will publish this somewhere else.

Thanks
