⚠️ Compatibility Notes

.NET 6.0 Warnings

During build, you may see warnings about some 9.x packages not being officially tested with .NET 6.0. These are informational warnings that suggest using .NET 8.0 for optimal support, but they do not prevent functionality.

Breaking Changes

• Minimum Framework: Projects now require .NET 6.0 or higher
• Package Dependencies: Applications consuming these packages must target compatible frameworks
• API Compatibility: All public APIs remain backward compatible

🏗️ Build & Deployment

Build Status

• ✅ Successful Build: All projects compile successfully
• ✅ Multi-target Support: Generates assemblies for both net6.0 and net8.0
• ✅ Package Generation: Creates NuGet packages automatically

Build Command

dotnet build

Build Output

• Projects successfully built in ~4 seconds
• 128 informational warnings (non-blocking)
• All target frameworks supported

📋 Migration Checklist

• Update all project target frameworks
• Modernize NuGet package references
• Replace obsolete packages with modern alternatives
• Update version numbers to reflect major changes
• Verify successful build across all targets
• Validate package compatibility
• Update project references
• Clean up deprecated dependencies
