What's the advantage of LaunchUriAsync over Process.Start to launch default browser with uri?

[TangDave]

On Windows, Process.Start has always launched the default browser just fine, but have run into some problems with Linux - is LaunchUriAsync designed to work on Linux more reliably? Is there a reason to prefer LaunchUriAsync even for Windows?

LaunchUriAsync is designed to abstract launching URI code from platform specific details. Even Process.Start doesn't have a specific right way to do that for all desktop platform, you need to write slightly different commands for different OS. And obviously it won't work for non-desktop platforms.

It should work. Not necessary more reliably, but definitely easier to use.
If there is a problem, you can report an issue.
