Portability Analyzer New -
Are you looking to run this assessment or automated in a CI/CD pipeline ?
Address existing compiler warnings in your legacy application before analyzing portability. Clean code ports much faster.
Microsoft consolidated its legacy migration utilities into the newer .NET Upgrade Assistant . This newer system performs the same core deep-binary evaluation while adding automated project file restructuring and source code modification features.
Modern portability analysis is fully scriptable via the .NET CLI. Teams can embed portability gates into their GitHub Actions or Azure DevOps pipelines. This ensures that legacy code patterns are flagged during pull requests, preventing developers from accidentally introducing non-portable APIs into a modernized codebase.

The analyzer generates detailed Excel spreadsheets, HTML reports, and interactive dependency graphs. These visual aids show exactly which architectural layers are tightly bound to a specific operating system. Key Benefits for Engineering Teams
What are you analyzing? (e.g., ASP.NET MVC, WinForms, Class Library)
While the old analyzer often looked at compiled binaries, the new assistant works directly with your source code, making the transition from analysis to implementation seamless. Why You Should Switch to the New Workflow Are you looking to run this assessment or
Targeting the rapidly growing EV market, the PW4001 offers ±0.04% basic accuracy, a 2.5 MS/s sampling rate, and a 600 kHz bandwidth—all in a DC-powered, road-ready package. It is built to comply with global testing standards like WLTP and SAE J1634 for certification and can be connected via CAN or OBD-II, making installation in a vehicle fast and safe. It is essential for engineers validating inverter efficiency and battery durability on the road.
The legacy tool required you to build your project and analyze the resulting .dll files. The new ecosystem operates directly on your source code and project files ( .csproj ). This allows the tools to identify not just incompatible APIs, but also outdated project configurations, broken NuGet dependencies, and systemic architectural blockers. 2. Interactive and Step-by-Step Guidance
Structural differences, such as migrating from global.asax files to the modern middleware pipeline in ASP.NET Core. Best Practices for a Seamless Migration Teams can embed portability gates into their GitHub
