awesome-avalonia VS Mapsui

WPF and Xamarin dev here who wrote a new (not ported) codebase on Avalonia.

- Avalonia has a guide just for people like you and me [1].

- Avalonia's flavor of XAML has small divergences from WPF that will have you hitting their docs often. There are some nice quality-of-life improvements, for example you can bind a Button click handler directly to a method without ICommand. The major concepts are the same e.g. data binding, dependency properties.

- Coming from WPF, it's possible you've used MVVM and dependency injection. You'd be going against a strong cultural grain to not use them in Avalonia. But I would be surprised if your WinForms app is architected remotely similarly, so it may be a design challenge extracting coherent ViewModels and properties from the ball of mud that many WinForms apps become.

- For macOS, read up on notarization [2] and, if you're publishing to the Mac App Store, the review process.

- I recommend starting with example apps (look in the Showcase) or with the Avalonia template solution which just runs out of the box.

- The Avalonia team iterates quickly. Expect to upgrade NuGets frequently, and don't get too far behind. There was recently a big jump from version 10 to 11. Good for you for starting after that.

- Not Avalonia specifically but if you're not used to .NET Core check out #nullable enable. Can't live without it now, but was confusing at first.

- Be sure to check out all of the official and community libraries [3]. I bet my design big on `ReactiveUI` and it's gone well.

I hear you. We’ve a decent datagrid and a load of OSS components that you can find here.

You can see a lot here and, for example, here

You can find more 3rd party controls here for example : https://github.com/AvaloniaCommunity/awesome-avalonia

More about Avalonia production apps here.

You could use Avalonia. This is xaml crossplatform and will be better supported than wpf. You can get the templates for dotnet new Avalonia. It's xaml, fast templates and there is a designer op github, can't fidn it atm. Some examples

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.
