The target framework of my application is .NET 6.0, and it will run on Windows, macOS, and Linux. I would like my application to prevent its host from entering sleep/idle mode while the application is performing certain tasks. I can achieve this on Windows by following steps such as this.

However, I am not sure how portable these steps are. MSDN page on SetThreadExecutionState reads:

Target Platform Windows

Does it mean the above-linked approach is not portable? if not, is there any universal approach for preventing the host system from entering the sleep/idle state?

Are you sure you want this method, instead of [GC.TryStartNoGCRegion](https://learn.microsoft.com/en-us/dotnet/api/system.gc.trystartnogcregion)? – JL0PD Jan 16 '22 at 09:06
I am not sure how disallowing garbage collection would prevent system sleep/idle. – Dr. Strangelove Jan 16 '22 at 09:39
No, it is not portable. https://unix.stackexchange.com/questions/437735/prevent-system-from-going-to-sleep-suspend-how-xviewer-vlc-do-it – Hans Passant Jan 16 '22 at 09:53
And I assume there is no portable alternative!? – Dr. Strangelove Jan 16 '22 at 18:30
