🎯 Version Number Auto-Increment Rules

Format: MAJOR.MINOR.PATCH (follows Semantic Versioning 2.0.0)

Increment Rules:

• 🐛 Bug fixes → Patch +1 (2.0.2 → 2.0.3)
• ⚡ Performance improvements → Patch +1 (2.0.3 → 2.0.4)
• ✨ New features → Minor +1 (2.0.4 → 2.1.0)
• 🎯 New framework support → Minor +1 (2.1.0 → 2.2.0)
• 💥 Breaking changes → Major +1 (2.2.0 → 3.0.0)

Pre-release Versions:

• Alpha: X.Y.Z-alpha.N
• Beta: X.Y.Z-beta.N
• RC: X.Y.Z-rc.N

Automated Validation:

• SemVer format validation
• Tag and csproj version consistency check
• Prevents duplicate version publishing

🚀 Automated Release Workflow

Trigger: Push a tag matching v* pattern

git tag v2.0.3
git push origin v2.0.3

Workflow (5-10 minutes):

1. validate-version (< 1 min) - Version format and consistency validation
2. build-and-test (2-5 min) - Multi-platform build (Ubuntu + Windows) and all unit tests
3. pack-nuget (< 1 min) - Build Release configuration and pack for 6 frameworks
4. publish-nuget (1-2 min) - Publish to NuGet.org with API key
5. create-release (< 1 min) - Create GitHub Release with extracted release notes
6. notify-success - Display success message with links

Security Features:

• GitHub Secrets protection for API keys
• Optional Environment approval workflow
• Multi-stage version validation
• Quality gates (tests must pass)

Configuration Required

GitHub Secret (Required):

• NUGET_API_KEY - NuGet.org API key for publishing

GitHub Environment (Optional):

• nuget-production - For approval workflow and access control

Benefits

• Efficiency: Automated process saves time, 5-10 minutes per release
• Quality: Multi-stage validation ensures release quality
• Consistency: Standardized process reduces human error
• Knowledge: Comprehensive documentation for team collaboration
• Maintainability: Clear guidelines and processes

Usage Example

To release version 2.0.3:

# 1. Update version in Chsword.Excel2Object.csproj
# 2. Update release notes in README.md and README_EN.md
# 3. Commit changes
git add .
git commit -m "chore: bump version to 2.0.3"
git push origin main

# 4. Create and push tag
git tag v2.0.3
git push origin v2.0.3

# 5. Monitor GitHub Actions (automatic)

Testing

The workflow YAML has been validated for syntax correctness. The release workflow will be triggered automatically when a tag is pushed to the repository.
