[work] — Portability Analyzer New

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.

It then compares these against a (OS distribution, kernel version, libc, CPU errata, filesystem layout, available system calls). The power of this tool lies in its specificity

Even the newest analyzers cannot solve three things: The analyzer would flag this as unavailable in

Today, we’re unveiling the (v3.0), rebuilt to detect portability issues earlier, explain why they matter, and suggest fixes with higher precision.

WASI preview2 introduces sockets , random , cli . A new analyzer detects if your Wasm module calls wasi:http/outgoing-handler (requires a Wasm runtime like wasmtime) vs. wasi:clocks (universal). It prevents deploying a Wasm module to a “pure compute” edge runtime that lacks HTTP proxy support.
