- **Package Installation**: Dual-source strategy (NuGet.org + GitHub Packages)
- **Development Builds**: Instructions for GitHub Packages authentication
- **CI Status**: Matrix testing status across Windows/Linux/macOS

## 🔄 Badge Updates
- ✅ **CI/CD Pipeline**: Cross-platform matrix testing status
- ✅ **Security Analysis**: CodeQL scanning and dependency review
- ✅ **Automated Publishing**: GitHub Packages development builds
- ❌ **Removed**: Deprecated Testspace badge

Ready for community testing with development packages! 🚀

🔧 **Workflow Trigger Improvements**

## ✅ **Removed Hard-coded Feature Branches**
- **CI Pipeline**: Only master branch + PRs (no temporary feature branches)
- **Auto Publishing**: Only master branch (stable development builds)
- **Manual Publishing**: Available from any branch when needed

## 🎯 **Benefits**
- **Maintainable**: No need to update workflows for every feature branch
- **Scalable**: Works for any future feature branches automatically
- **Clean**: CI only runs at integration points (master + PRs)
- **Efficient**: Eliminates duplicate workflow runs

## 🚀 **Result**
- ✅ Follows GitHub Actions best practices
- ✅ Reduced maintenance overhead
- ✅ Clean separation of concerns
- ✅ Ready for production use

CI/CD modernization is now production-ready! 🎉

🎯 **Mono Runtime Modernization**

## 📰 **Context**: Microsoft Mono Project Transition
- Original Mono Project → Moving to WineHQ stewardship
- Microsoft's modern Mono fork → Integrated into dotnet/runtime
- .NET 8+ includes built-in Mono runtime for cross-platform .NET Framework support

## ✅ **Cross-Platform .NET Framework Support**
- **Linux**: Now runs net472 tests using built-in Mono runtime
- **macOS**: Unified test execution (no more custom XUnit/Mono logic)
- **Windows**: Unchanged (native .NET Framework support)

## 🔧 **Build System Improvements**
- **Simplified Logic**: Removed platform-specific workarounds
- **Unified Execution**: Same \`dotnet test\` command across all platforms
- **Dependency Elimination**: No external Mono installation required
- **Better Coverage**: Full framework testing on all platforms

## 🚀 **CI/CD Enhancements**
- **Matrix Testing**: Added net472 to Linux/macOS matrix
- **Trigger Fix**: Added feature/* pattern for testing
- **Modern Runtime**: Leverages .NET 9.0.200 built-in Mono

## 📈 **Result**
- ✅ True cross-platform .NET Framework support
- ✅ Simplified, maintainable build system
- ✅ Zero external runtime dependencies
- ✅ Enhanced test coverage across all platforms
