Mapsui VS Avalonia

But I think some of this stuff is already handled in Avalonia ecosystem like https://github.com/Mapsui/Mapsui, https://github.com/beto-rodriguez/LiveCharts2 and few others...

Release 4.0.0 · Mapsui/Mapsui (github.com)

You are probably using Xamarin.Maps that use native maps, Google Maps on Android and Apple Maps on iOS, I assume. In Windows there's no native map, so you would need some third party library. I would recommend Mapsui

... private static void MapOnInfo(object? sender, MapInfoEventArgs e) { var calloutStyle = e.MapInfo?.Feature?.Styles.Where(s => s is CalloutStyle).Cast().FirstOrDefault(); if (calloutStyle != null) { calloutlist.Add(calloutStyle); foreach (var callout in calloutlist) { callout.Enabled = false; } calloutStyle.Enabled = !calloutStyle.Enabled; e.MapInfo?.Layer?.DataHasChanged(); // To trigger a refresh of graphics. } if (calloutlist.Count > 1) calloutlist.RemoveRange(0, calloutlist.Count - 1); } private MemoryLayer CreatePointLayer() { return new MemoryLayer { Name = "Points", IsMapInfoLayer = true, Features = new Mapsui.Providers.MemoryProvider(GetPlacesFromList()).Features, Style = SymbolStyles.CreatePinStyle() //<- Reference for custom marker: https://github.com/Mapsui/Mapsui/blob/master/Samples/Mapsui.Samples.Common/Maps/Callouts/CustomCalloutSample.cs#L64 }; } ... private static CalloutStyle CreateCalloutStyle(string? name) { return new CalloutStyle { Title = name, TitleFont = { FontFamily = null, Size = 12, Italic = false, Bold = true }, TitleFontColor = Color.Violet, MaxWidth = 120, RectRadius = 10, ShadowWidth = 4, Enabled = false, SymbolOffset = new Offset(0, SymbolStyle.DefaultHeight * 0.3f) }; }

Looking through their getting started page and their examples on Github (specifically: SingleCalloutSample) I was able to get my list of places to show up on the map and when clicked display certain features.This has led to me only being able to toggle whether the callout is displayed or not. What I am hoping to figure out is how to disable all other callouts once another location is selected, so that only a single callout is displayed at a time.

Json.net, MahApps.Metro, and MapsUI

So I did a quick DDG search and found these two results. Link 1. Link 2. Good luck.

You might also want to look at AvaloniaUI[0] for a cross platform .NET GUI library. It is similar to WPF but much nicer to work with.

Production user here. There's no money gotchas. They're above reproach. In fact, I've received considerable free support from their devs on GitHub Issues [1].

The Avalonia business model is based on selling XPF, which runs WPF (Windows-only) apps on other platforms. That's very interesting to big corps with existing codebases.

Yes, but the portable GUI frameworks by Microsoft themselves are generally not very good, and they tend to be abandoned after a couple of years.

Avalonia is developed outside of the Microsoft corporate madness and seems to be slowly becoming the defacto cross-platform framework because it is expected to last a bit longer than a manager's attention span: https://avaloniaui.net/

Not my comment, but relevant here "The problem with compiling Skia to WASM is you'll lose any benefits of hardware graphics acceleration on the device."

(From https://github.com/AvaloniaUI/Avalonia/discussions/6831#disc... )

It's a bit of a hit and miss as of today. CLI, back-end and natively compiled libraries (think dll/so/dylib or even .lib/.a - you can statically link NAOT binaries into other "unmanaged" code) work best, GUI - requires more work.

Avalonia[0] and MAUI[1] have known working templates with it, but YMMV.

For desktop, Avalonia, hands down.

Open source, powered by Skia, backed by JetBrains, and quite battle-tested at this point for small to medium-sized apps. In theory perfectly capable for enterprise as well, since it's basically a spiritual successor to WPF, which has been an industry standard for about 15 years.

They're diving into mobile and WASM well, but that's more of a recent effort and I haven't tested that yet.
