Is there an existing issue for this?

Current Behavior

Getting this error upon App launch on the Windows platform configured with Maps.

“Method not found: ‘Void Microsoft.Maui.Platform.MauiWebView…ctor()’.”

Expected Behavior

Quite like .NET 7, the app is expected to launch with the Maps view loaded on the underlying WebView.

Steps To Reproduce

1. Created an MAUI app on .NET 8 Preview 5
2. Added the newly released “CommunityToolkit.Maui.Maps” NuGet package
3. Chained the extension method in the App startup
4. Set Windows as the target platform and tried to launch the app

Link to public reproduction project repository

Default template of .NET 8 is suffice, just add Map control to the Main page

Environment

- .NET MAUI CommunityToolkit: 1.0.0 (CommunityToolkit.Maui.Maps package)
- OS: Windows 11 (10.0.22621.1778)
- .NET MAUI:.NET MAUI on .NET 8 Preview 5 (8.0.0-preview.5.8529)

Anything else?

It works fine on .NET 7, facing this issue only on .NET 8.

@egvijayanand we didn’t test it with the preview, we test things with the stable .NET MAUI bits, that is why it wasn’t in there. We weren’t aware. Thanks for testing it, it’s in the release notes now.

And no one here is expecting everything to work in the preview release, just to know whether it’s supported or not.

If there’s a mention, no one would touch that part.
