Does anyone know of a library I can design UI in HTML/CSS/JS for a C# app?

I need to remake my bot framework, but winforms is just so old.

Why not WPF?
Using XAML (similar to XML), but still way better than the old WinForms.

@JS96 Because my app defies MVVM, MVC or any other pattern due to fact there are no resources to manage.

@HelloUglyWorld
WPF is too hard for begineers.
Maybe Razor? ASP.NET?
Or you can make Electron/React apps using Bridge.net
https://bridge.net

@CozyPlanes Beginners?

Why does everyone imply I'm a begineer because I don't want to use MVVM where it wouldn't be effective?

I have over 4 years of professional C# experience, what is going on?

I sm sure you can write spageti code with WPF too so why you dont give it shot?

@Kekica That's exactly the reason I don't want to write it in WPF - because it'll come out as spaghetti code.

I was joking but ok, what is your bot framework written in now?

@Kekica Winforms.

Why not make your bot framework an api then give it a front end to call it with. You can have your app start the api and open a browser from on the start page

Really, if it is a windows only application there is NO justification to not use WPF. Xaml is great!

And btw, if you did not use Xaml until now you are per definition a beginner in this regards! Xaml is not C#!

@gruff It's a desktop app, C#, .NET.

@geaz As I said, 3 times already.
I've used WPF - a lot.
I know WPF, very well.
That's why - I don't want to use it for this project, because it would force MVVM pattern and it would be terribly ineffective in this case.

@HelloUglyWorld I can't see a single comment where you mentioned that you know WPF ;)

Furthermore I don't understand how MVVM would be inefficent. What do you want to do within a HTML/JS/CSS solution? Writing spagethi? Most of the web UI frameworks are using MVVM for the UI, too.

@HelloUglyWorld a bit of overkill but maybe use unity and make your fancy modern ui via its ui tools?

Use the webbrowser widget and use HTML/CSS/JS there :^)

@geaz I enjoyed using CefSharp for frontend and C# for backend, hence why I thought there definitely has to be an up-to-date library that I could use to separate frontend and backend by language.

@HelloUglyWorld You can still host an api with your app

@Midnigh-shcode Yeah, a bit of an overkill.

@HelloUglyWorld i meant wpf is hard to learn for those who never learned wpf before

Maybe use https://retyped.com ?
