 # The .NET Portability Analyzer
 
 [!INCLUDE[](~/includes/deprecating-api-port.md)]
 
-Want to make your libraries support multi-platform? Want to see how much work is required to make your .NET Framework application run on .NET Core? The [.NET Portability Analyzer](https://github.com/microsoft/dotnet-apiport) is a tool that analyzes assemblies and provides a detailed report on .NET APIs that are missing for the applications or libraries to be portable on your specified targeted .NET platforms. The Portability Analyzer is offered as a [Visual Studio Extension](https://marketplace.visualstudio.com/items?itemName=ConnieYau.NETPortabilityAnalyzer), which analyzes one assembly per project, and as an [ApiPort console app](https://aka.ms/apiportdownload), which analyzes assemblies by specified files or directory.
+Want to make your libraries support multi-platform? Want to see how much work is required to make your .NET Framework application run on .NET Core? The [.NET Portability Analyzer](https://github.com/microsoft/dotnet-apiport) is a tool that analyzes assemblies and provides a detailed report on .NET APIs that are missing for the applications or libraries to be portable on your specified targeted .NET platforms. The Portability Analyzer is a [console app](https://aka.ms/apiportdownload) that analyzes assemblies by specified files or directory.
 
 Once you've converted your project to target the new platform, like .NET Core, you can use the Roslyn-based [Platform compatibility analyzer](platform-compat-analyzer.md) to identify APIs that throw <xref:System.PlatformNotSupportedException> exceptions and other compatibility issues.
 
 ## Common targets
 
-- [.NET Core](../../core/introduction.md): Has a modular design, supports side-by-side installation, and targets cross-platform scenarios. Side-by-side installation allows you to adopt new .NET Core versions without breaking other apps. If your goal is to port your app to .NET Core and support multiple platforms, this is the recommended target.
-- [.NET Standard](../net-standard.md): Includes the .NET Standard APIs available on all .NET implementations. If your goal is to make your library run on all .NET supported platforms, this is recommended target.
-- [ASP.NET Core](/aspnet/core): A modern web-framework built on .NET Core. If your goal is to port your web app to .NET Core to support multiple platforms, this is the recommended target.
-- .NET Core + [Platform Extensions](../../core/porting/windows-compat-pack.md): Includes the .NET Core APIs in addition to the Windows Compatibility Pack, which provides many of the .NET Framework available technologies. This is a recommended target for porting your app from .NET Framework to .NET Core on Windows.
-- .NET Standard + [Platform Extensions](../../core/porting/windows-compat-pack.md): Includes the .NET Standard APIs in addition to the Windows Compatibility Pack, which provides many of the .NET Framework available technologies. This is a recommended target for porting your library from .NET Framework to .NET Core on Windows.

 ## How to use the .NET Portability Analyzer
 
-To begin using the .NET Portability Analyzer in Visual Studio, you first need to download and install the extension from the [Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=ConnieYau.NETPortabilityAnalyzer). It works on Visual Studio 2017 and Visual Studio 2019 versions.
+To begin using the .NET Portability Analyzer in Visual Studio, you first need to [clone and build the dotnet-apiport project](https://github.com/microsoft/dotnet-apiport/blob/dev/docs/Console/README.md#run-the-tool-in-an-offline-mode). It works on Visual Studio 2017 and Visual Studio 2019 versions.
 
 > [!IMPORTANT]
 > The .NET Portability Analyzer is not supported in Visual Studio 2022.
 
-Configure it in Visual Studio via **Analyze** > **Portability Analyzer Settings** and select your Target Platforms, which are the .NET platforms/versions that you want to evaluate the portability gaps comparing with the platform/version that your current assembly is built with.

+A useful step in analyzing a solution with many projects is to visualize the dependencies to understand which subset of assemblies depend on what. The general recommendation is to apply the results of the analysis in a bottom-up approach starting with the leaf nodes in a dependency graph.
 
-You can also use the ApiPort console application, download it from [ApiPort repository](https://aka.ms/apiportdownload). You can use `listTargets` command option to display the available target list, then pick target platforms by specifying `-t` or `--target` command option.

If it's an assembly that you own, include it in the API portability analyzer run so that you can get a detailed, API-level portability report for it.
