TKCode.Arc.Special 1.0.0

TKCode.Arc

English | 简体中文

The visual language and spring motion of Arc, as native Avalonia controls.

TKCode.Arc is a UI kit for .NET applications on Avalonia 12. It ports Arc's 112 free components and adds what a full product needs around them: page-level blocks, a spreadsheet-style data grid, a workflow canvas, IDE-style docking, a terminal, a PDF viewer, and audio and video playback.

Why Arc

• Native controls. Every control derives from Avalonia base types and uses public Avalonia APIs only.
• One token system. Colors, radii, shadows and fonts come from design tokens, so light and dark, the eight accent presets and whole-theme packages apply across every control.
• Motion built in. A spring engine drives the components, with Full, Reduced and Off levels for the whole app.
• Ready for NativeAOT. The libraries are built as trimming and AOT compatible.
• Documented in three languages. Each of the 300+ component and block pages has live examples and a generated API table, in English, 简体中文 and 繁體中文.
• Readable by AI assistants. The site publishes llms.txt, every page as Markdown and an agent skill.

Status and compatibility

Arc follows Semantic Versioning: from 1.0.0 on, breaking API changes come only with a new major version. CHANGELOG.md lists each release and its migration notes.

Repository

Working on the library

Building needs the .NET 11 SDK (see global.json) and the .NET 10 runtime, which the tests and the gallery run on.

dotnet build TKCode.Arc.slnx
dotnet test tests/TKCode.Arc.Core.Tests
dotnet test tests/TKCode.Arc.Foundation.Tests
dotnet test tests/TKCode.Arc.Tests
dotnet run --project gallery/TKCode.Arc.Gallery.Desktop -f net10.0

PDFium and pdf.js are not committed: tools/pdf/sync-native.sh and tools/pdf/sync-pdfjs.sh download them and check their checksums. Without them the desktop gallery shows a simulated document in the PDF demos, and a browser build has no pdf.js to import.

Project rules and conventions are in AGENTS.md.
