Thank you!

I believe the error is correct:

The XUnit project is net8.0. MAUI UI Single Project files reference individual platforms (net8.0-android, etc). You're trying to reference that project inside a non platform specific project, which won't work. It's not a MAUI issue, it's how Target Frameworks operate. You would hit similar issues if you were trying to reference net8.0-android class libraries inside a net8.0 XUnit project.

If you're trying to do UnitTests on non-UI parts of your code, I believe the best thing to do would be move them into another class library that's not platform specific (net8.0, net7.0, netstandard2.0 etc) and reference that instead. Otherwise, you would need to set up a device test runner and run them on the actual platform.

CC @BretJohnson @PureWeen is there anything else they could do? I know there's a bunch happening right now in the repo with XUnit and device testing.
