Eto.Forms VS ScintillaNET

An option that does not seem to have been mentioned yet is Eto.Forms: https://github.com/picoe/Eto

And the above is caused by https://github.com/picoe/Eto/issues/2361

Eto Forms - Simple cross-platform UI toolkit using native components, also for F# - https://github.com/picoe/Eto

Yes, you can use Eto.Forms. There is also Windows Forms (with WYSIWYG editor).

Check out Eto Forms

Look at the Wiki: Containers

To move on to GUI dev, there's the Qt Framework, Eto.forms for C#; Rust has the ImGui wrapper for the C++ Dear ImGui library.

I'm using the ScintillaNET NuGet package. It had its last update 6 years ago. Its last repo commit 5 years ago. The documentation... is lacking - for example, copying example code from there immediately gave me obsolete warnings. Still, this was simply the only library I could find for this.

If you're using Windows Forms, you can also take a look at ScintillaNET (or for WPF inside of a WindowsFormsHost).

It’s actually WinForms 😄. I’m using dockpanelsuite, DarkUI, and ScintillaNET. I forked the dockpanelsuite and DarkUI repos. My modifications to dockpanelsuite adds a docking manager and ability to use extra (non-default) theme files from a vstheme.gz format that the documentation specifies. I then extended DarkUI to accept ThemeBase objects and apply the necessary drawing/coloring styles to the controls.
