cui-32xMigrating from CuoreUI?

HartUI is based on CuoreUI.Winforms. Most projects should require only a few changes to migrate.

  1. Uninstall the CuoreUI.Winforms NuGet package.
  2. Install HartUI.Winforms.
  3. Replace CuoreUI namespace mentions with HartUI. (In most cases, Find & Replace will work just fine)
  4. Rebuild your project.

📜 Documentation

No full-fledged documentation for the foreseeable future. The library is intuitive enough that you should know your way around if you've worked with frameworks like GunaUI or SiticoneUI before.

If you still want to see the old documentation, it's available on the forked website: hartui.netlify.app/docs

The docs will either be removed or rewritten over time.

📅 Versioning

We use CalVer.
