Dotnet Upgrade

A comprehensive prompt collection for modernizing .NET projects from Framework to .NET 8. Covers the full upgrade lifecycle from dependency analysis and packages.config migration to CI/CD pipeline updates and breaking change detection. The prompts guide you through project classification, upgrade sequencing, PackageReference conversion, and build validation. Honest take: this is thorough but heavy. You'll want to cherry-pick prompts based on your solution complexity rather than running through everything. The branching strategy and documentation prompts are solid additions that most upgrade guides skip.
