The is not a single tool but an orchestration framework that models portability as a three-dimensional continuum:

Whether you are transitioning legacy systems to cloud-native environments or moving projects to updated framework versions, this tool simplifies architectural assessment. What is the New Portability Analyzer?

The power of this tool lies in its specificity. It does not merely state that a project is incompatible; it identifies exactly where the incompatibility lies. For instance, a developer might learn that their application relies on System.Web.HttpContext , an API deeply rooted in the legacy Windows-only framework. The analyzer would flag this as unavailable in .NET Core, forcing the developer to seek a modern alternative, such as middleware in ASP.NET Core. This granular visibility allows teams to estimate the cost of migration with a degree of accuracy that would otherwise be impossible.

: You can compare your code against multiple targets simultaneously, such as .NET Standard , .NET Core , or Mono .
