@richlander PTAL at my comments regarding Process and SafeFileHandle

([dotnet/runtime #125512](https://github.com/dotnet/runtime/pull/125512)). On
Windows, `Process` now uses overlapped I/O for redirected stdout/stderr, which
reduces thread-pool blocking in process-heavy apps
([dotnet/runtime #125643](https://github.com/dotnet/runtime/pull/125643)).

dotnet/runtime#125848 was also merged as part of Preview 3, combined with other new low-level SafeFileHandle APIs it allows for redirecting standard handles to any file which opens up new scenarios such as:

  • process piping,
  • redirecting output to a file,
  • discarding output by redirecting to a null handle,
  • starting process with no input,
  • starting process with async handles (advanced, needed by PowerShell).

FWIW I am planning to release a dedicated Process blog post when I am done with all the changes, so we don't have to include it here. But I would definitely not mind including it here.

Are you sure? This looks like the VMR merge code-flow commit: dotnet/dotnet@8074748

That was to main. Did it make it to p3 a different way?

Did Support HTTP Query #65714 make it into preview3? If so it seems to be missing from aspnetcore.md.

@mikekistler I don't believe this change made it. I think the PR is in the wrong milestone.
