The has been deprecated. It is replaced by the .NET Upgrade Assistant , which allows you to modernize applications piece-by-piece using a new "side-by-side incremental" approach. The "New Proper Piece" Strategy

The modernization ecosystem is structured around several distinct shifts:

Choose the selection to generate a real-time compatibility matrix highlighting your migration paths. 🎯 Strategic Best Practices

Using Roslyn analyzers, the tools now offer live, "as-you-type" analysis. This means developers can identify APIs that throw PlatformNotSupportedException in real-time, long before the migration testing phase. 3. Targeted Platform Selection The has been deprecated

For years, developers relied on the classic .NET Portability Analyzer (often referred to as API Portability or ApiPort ). It was available as both a Visual Studio extension and a command-line tool. It did one job well: it scanned compiled assemblies and generated an Excel or HTML spreadsheet showing which APIs were supported on target platforms like .NET Core, .NET Standard, or Xamarin.

Manual code reviews, grep-ing for known legacy APIs, and trial-and-error compilation. Choose the selection to generate a real-time compatibility

Running analysis required building the project first, which could be difficult if the project was already partially broken during a migration.

Heavy architectural reliance on app-domain isolation schemes, which have been replaced by isolated process execution architectures.

Before running the scan, define your desired end state. You must specify your target framework version and target operating systems. Setting explicit targets prevents the report from cluttering with irrelevant compatibility warnings. Step 3: Run the Scan
