| description | Structured guidance for assessing and executing modernization from .NET Framework or older .NET targets to modern .NET. USE FOR: inventory a legacy .NET solution, plan phased .NET upgrade, review NuGet and framework compatibility, define modernization test and release gates, remediate breaking changes during migration. DO NOT USE FOR: brand-new .NET app scaffolding, non-.NET platform migrations, day-to-day feature development unrelated to upgrades. |
