Note that you can't zoom to a point - you can pan to it, but to zoom, you'll need the overload of Viewpoint that takes a scale as well. This is because the point has an infinitely small size, so we wouldn't know how far to zoom in. It really depends on what the point represents (building, address, city, etc). Wrt Already Owned exception: A map can only be active with one MapView at a time. Are you using the map with multiple mapviews? Also note that if the garbage collector hasn't had a chance to clear out the old mapview yet, the map might still be associated with the mapview. A good way around this is when a mapview closes, to unhook the map immediately from the mapview, so it's ready for use on the next one.

There is no location where you tapped on the line. The identify is done with some pixel tolerance and finds any geometry intersecting within that distance visually. Since a line is infinitely thin, you most likely didn't actually click the line but right next to it. The identify operation is all done in the rendered pixel space, so the calculation for where they intersect isn't ever made. The best you get is to nearest vertex like @GKmieliauskas points out. I get that gets tricky in 3D since you're really talking about the nearest point between the polyline and the ray from the camera to the location on the surface. There's no out-of-the box way to calculate this position, so you might be in for doing a little bit of 3D trigonometry between those two line segments.

I just retried the repro on 200.4, then upgraded to 200.5 on Maui WinUI and observed the problem go away. Could you try doing a full clean and forced rebuild, to make sure no old 200.4 assemblies are left around?

There's unfortunately not much we can do about .NET's own first chance internal exceptions occurring when we cancel requests. The main problem is that the Visual Studio debugger cause significant slow down monitoring these, and Microsoft has not been willing to address it. We tried also not cancelling requests while the debugger is attached, but that causes separate performance issues because we might be loading way more tiles than you ever need. Rest assured this is not an issue when running without the debugger attached, and you'll see much better performance when not debugging, and your users won't be affected.

I think I see what you're getting at but not 100% sure. Could you provide a small application that demonstrates the problem that we can use to investigate?

Attached a runnable sample. I left the "old" WebBrowser class in there too so you can compare the differences. They are mostly pretty minor

GeoBlazor is awesome, but I don't believe it supports offline, since it's just a blazor wrapper of the JS API.

I can reproduce the issue. Looks like the oauth dialog made a change making it incompatible with WPF's default Internet Explorer browser. I've started an issue internally to see if we can't get that fixed. You could look into using WebView2 instead of the default browser control which doesn't seem to be affected.

You can't host MAUI UI Controls inside the Blazor pages (AFAIK it only works the other way around that you can host the BlazorWebView inside a XAML page)

Could you zip up a running project and attach here, so we can try and reproduce your issue? It's a little hard to gauge from the small screenshot what the expectation and behavior is.

Apart from overriding the symbol or rendering a second symbol in a graphic overlay to highlight it, I can't think of any no.

Leave the referrer blank and it should work. I reproduced putting in a * will break it. You can also specify an actual referrer url like this: And then in the app configure it to use that referrer: Also make sure you enable at least the basemap service (and anything else you plan on using the key for)
