Uno Platform VS CSharpForMarkup

And Uno Platform (https://platform.uno/) is akin to React Native in terms of native controls usage.

also UNO Platform (C#) which is suitable for simple or complex cross platform business applications : https://platform.uno/

Why is this a problem? At face value, it isn't a problem. Taking a step back at a more global level, what does "uComponents" mean to the rest of the world? Many of the .NET developers who heavily use NuGet may have not even heard of Umbraco CMS, let alone a 3rd party plugin for it. What if people from the Uno Platform community are browsing NuGet for some kind of components extension library? You can see, this could get confusing outside the scope of the Umbraco community/ecosystem. On top of this, uComponents was developed against Umbraco v4, with its last release in 2016, now it's there to be lingering on the NuGet repository until the end of time, set in stone.

Not a fan of XAML after trying to get into it, but there is Uno Platform. It wraps native widgets on mobile, just like React Native (which is good for accessibility), and uses C#. https://platform.uno/

My guess is that it's mainly focused on mobile. On Windows, it has no overhead (behaving like a normal WinUI 3 app), on macOS I think it uses Catalyst by default (which was developed by Apple to make more iOS apps available for Mac desktops) and on Linux it draws its own widgets that the devs try imitating the GTK style with.

On Android and iOS, it just uses the native widgets which I think is a better experience so you can see my reasons for guessing it's mobile-first. That may or may not be what you want.

> ...building UIs with the document/element api

When the whole premise is flawed, JSX or not, does it really matter if there is a better or worse way of misusing a technology not meant for UIs?

Leave HTML and JavaScript to Wikipedia and other hypertext document libraries.

Unfortunately, WASM is not there yet, but people are trying: https://platform.uno.

Uno Platform is fully open source, under Apache 2.0 license. You can see the license here https://github.com/unoplatform/uno/blob/master/License.md

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.

Uno Platform can be both XAML or C# Markup if you use https://github.com/VincentH-Net/CSharpForMarkup with it.

And if you use https://github.com/VincentH-Net/CSharpForMarkup with it, you can have an all-around C# approach for both front end and back end.

Maybe some c# markup libraries like this one. But I haven't use that so you'd need to check yourself

You can CSharpForMarkup with WPF, WinUI 3, Uno Platform. with AvaloniaUI and Maui coming and possibly Blazor.

To manage mental mapping of what is being drawn, I keep methods that create widget trees short. My rule of thumb is that whole method has to comfortably fit the screen at once. For each section of the main tree I create a static function that returns a branch of the tree. These functions have descriptive names that help you visualize what element each function builds. If a tree inside a function is long, it is broken down in the same way.

There are some fluent extensions (for Xamarin.Forms and probably future MAUI) that help you build UI in declarative fashion with C#. Same extensions could be created for other frameworks.

For reusable custom widgets that can't be done with a static function, I create new classes with their own widget trees. Try to keep widgets composable and avoid inheritance if possible.

Hot reload is coming in .NET 6, so waiting for rebuild will soon be history.

I have no experience with QML so I can't really comment on that.

If I were to build a windows only desktop app with technology I was moderately familiar with, I'd probably got for WPF + https://github.com/VincentH-Net/CSharpForMarkup Working without XAML makes life so much simpler.
