Build Configuration Rules

Windows Target Framework Moniker (TFM)

CRITICAL: When configuring projects to target Windows, use the explicit TFM format that includes the platform version: net10.0-windows10.0.26100.0

Do NOT use: <TargetFramework>net10.0-windows</TargetFramework> with a separate <TargetPlatformVersion>... property. This is required to avoid "Windows Metadata not provided" errors during full solution builds with CsWinRT.

SkiaSharp Version Guidance

IMPORTANT: SkiaSharp is centrally managed in the root Directory.Packages.props and is currently on 3.119.3-preview.1.1 for the Avalonia 12 upgrade line.

• When adding SkiaSharp to a new project, prefer the shared central package version instead of introducing an inline project-local version.
• If you encounter version conflicts, align with the root central package management entry rather than reintroducing the legacy 2.88.9 pin.
• This guidance applies to all projects including XerahS.* and ShareX.ImageEditor.

General Coding Rules

Code and Config Changes

• Follow existing patterns in each project area.
• Keep changes minimal and targeted.
• Add small comments only when necessary to explain non-obvious logic.
• CRITICAL: After modifying code, always run dotnet build and fix all build errors before finishing.
• For Git workflow, commit format, and version bump behavior, follow .ai/skills/git-workflow/SKILL.md.
• Ensure you can compile, and if not, fix the issues. This is a mandatory check before finishing any coding task.

Change Safety

• Do not remove or rewrite unrelated content.
• Apply version changes only via the workflow defined in .ai/skills/git-workflow/SKILL.md.
• Flag assumptions clearly when requirements are ambiguous.

Testing

• If you modify executable code, suggest relevant tests.
• If tests are added, align them with current test conventions.

Documentation

• Update or add docs when behavior or usage changes.
• Keep filenames and headings descriptive and stable.
• Technical Documentation Location: Automatically save all technical .md files that do not properly belong to other specific docs/ subfolders in docs/technical. Do not save them in the root folder.
• Commit expectations for documentation follow .ai/skills/git-workflow/SKILL.md.

Security

• Do not include secrets or tokens.
• Avoid logging sensitive data in examples.

Output Format

• For changes, summarize what changed and where.
• Provide next steps only when they are natural and actionable.
