Running Unoplatform application on autostart CM4

Discussed in #16716

Hello, I'm trying to run a Uno Platform application on autostart with FRAMEBUFFER=/dev/fb1, but I'm encountering the following issue: 'Unhandled exception. System.InvalidOperationException: Cannot read keys when either the application does not have a console or when console input has been redirected. Try Console.Read.' Has anyone encountered this issue before?

Thanks for the report! This is indeed a behavior that is found in

uno/src/Uno.UI.Runtime.Skia.Linux.FrameBuffer/FramebufferHost.cs

Lines 86 to 87 in a713fc5

	Console.ReadKey(true);
	}

Where the app expects to be started from a terminal, in order for it to be stopped by the user.

There could definitely be a sub-builder option in the console builder that avoids this behavior in:

uno/src/Uno.UI.Runtime.Skia.Linux.FrameBuffer/Builder/HostBuilder.cs

Line 11 in a713fc5

public static ISkiaHostBuilder UseLinuxFrameBuffer(this ISkiaHostBuilder builder)

Hi, I have the same problem. And our Project hungs on that point to be ordered by the customer.
Should there be a solution soon for that?
I've tried to resolve the problem and to publish a pull request if it works, but my enviroment seems to not be correct. I have build the sources and exchanged the uno dlls from my App with the new builded. It runs without error but without displaying anything. And that without changing any code for the first test.

This issue will be fixed by #16750, you'll be able to test it with the uno.sdk prerelease builds once it's merged.
