: If you still need the specific Excel or HTML reports from the original tool, you must use it in offline mode , as Microsoft has shut down the backend service. The .NET Portability Analyzer - Microsoft Learn
Use the command ApiPort.exe analyze -f [path-to-binaries] .
: This is the current "best practice" for complex applications. Instead of porting the entire codebase at once, you create a new .NET project that sits alongside your existing .NET Framework app.
A portability analyzer evaluates source code, dependencies, build configurations, and runtime assumptions to determine how easily a software project can be moved between environments (platforms, OS versions, architectures, container runtimes, cloud providers) or upgraded (language/runtime versions). This handbook explains goals, scope, methodology, metrics, common portability issues, remediation patterns, example analyses, and an actionable checklist to run or build a portability analyzer tool named "portability analyzer new". portability analyzer new
Review the generated compatibility report. Focus heavily on:
To meet this demand, development teams rely on specialized code assessment tools. The represents the next generation of these tools. It helps developers evaluate readiness, identify compatibility gaps, and streamline software migration. What is the New Portability Analyzer?
The "new" portability analyzer is not just a single reporting tool. It is an integrated, actionable suite designed to accelerate application modernization. By shifting from passive analysis to active assistance, tools like the .NET Upgrade Assistant remove the guesswork from upgrading your codebase. : If you still need the specific Excel
It supports complex upgrades, including transitioning legacy WCF services to modern CoreWCF or gRPC alternatives. 2. AWS Toolkit for .NET Refactoring
Whether you are moving from legacy .NET Framework to modern .NET 8/9, or transitioning workloads to cloud-native environments, understanding how the new generation of portability analysis works is essential for a smooth migration. What is the New Portability Analyzer?
The "new" way to handle portability is via the , which includes a dedicated "Analyze" mode: Instead of porting the entire codebase at once,
A list of specific non-portable APIs and recommended alternatives. Benefits of Portability Analysis The .NET Portability Analyzer - Microsoft Learn
It provides a detailed, granular roadmap, reducing the time spent analyzing dependencies.
The new generation of analysis capabilities operates entirely client-side. Legacy versions required active connections to external servers to resolve API compatibility. The latest toolsets download comprehensive localized API catalogs directly onto your device, allowing secure infrastructure audits within closed enterprise environments. 🛠️ Key Capabilities of Modern Portability Assessment Legacy Portability Analyzer ( ApiPort ) New .NET Upgrade Assistant / Modern Analyzers Binary-only (IL assembly scanning) Source code, project structures, and binaries Cloud Dependency Required backend API web services 100% Offline via local catalog definitions Visual Studio Support Limited to VS 2017 & VS 2019 extensions Full integration into VS 2022 & CLI environments Remediation Action Generates static reports (Excel/HTML) Executes automated code & dependency refactoring 📈 Deep Dive: Running a Portability Assessment
It helps developers determine the best target—whether that is moving to a modular .NET environment or fully embracing cross-platform compatibility.
