DetourWinUI.dll — classic WinForms UI (optional)

Drop it next to DetourLite.exe. It is loaded at startup, giving you the same window interface as the old Detour build.

How it works: DetourLite itself targets plain net8.0 (it must, to run on Linux — referencing WindowsDesktop would make the app refuse to start there). This DLL targets net8.0-windows and is loaded by DetourLite through runtime reflection, resolving WinForms assemblies on demand from the installed Microsoft.WindowsDesktop.App shared framework. So: on Linux this file is never touched; on Windows, omitting it costs you nothing but the classic window.

Requires the .NET 8 Desktop Runtime (not the plain runtime).

Localization: the bundled en/ ja/ zh-Hant/ folders are satellite assemblies holding the translated UI strings. Copy them along with the DLL, otherwise the UI falls back to Simplified Chinese.
