Hi @Brian Rawlings ,
Welcome to Microsoft Q&A!
Which version of Visual Studio are you using? Could you tell me how you got this error message? What is your project type?
Please update your VS to the latest version and create a new project to verify if it persists.
You can try to clean and rebuild your solution.
Sincerely,
Anna

I am using Visual Studio 2022, I have also tried reinstalling everything but it made no difference. The project is a sample walkthrough from microsoft.. The message came up when I ran Debug. I tried a clean and rebuild got the same message. Think I'll just leave it for now as I was just having a play in an area new to me.

After reinstalling and updating several times "Windows App SDK", nothing worked...
The only thing that worked for me was going to Nuget Package Manager and update all packages in the tab "Updates". (Example: Microsoft.Maui.Controls, etc....)
It worked!!!
Good luck!
Thank you.

I'm using the current latest stable version of Visual Studio 17.7.4, and have faced with a familiar problem of warning lines:
DEP0840: Project 'XXX' requires packages 'MicrosoftCorporationII.WinAppRuntime.Main.1.3_8wekyb3d8bbwe' and 'MicrosoftCorporationII.WinAppRuntime.Singleton_8wekyb3 ...
These packages should be installed on first run, if not please visit
TO HANDLE IT, visit the (http://go.microsoft.com/fwlink/?linkid=2222757) between lines, download the appropriate version of Windows App Runtime Installer on your PC and run it.
Then, in Build of your VS toolbar, click Clean Solution, and make sure to click Rebuild Solution TWICE. This is because with once clicking, the VS won't instantly response to the project changes.
If you find above steps don't help, try click build each time before you launch the app on Local machine or anywhere supported.
This would miss the warning line that occurs after stopping the launch each time, though I don't know why this line would occur.
If you find steps above doesn't help, build every time before you launch the app on local machine or anywhere supported in VS.
This would errase the warning message to comfort you with 0 errors reported, though in my experience it may not raise any tricky problems?
