From the error, maybe your project isn't consistent on whether 19041 or 22000 is the target?

Can you update to the latest .NET SDK released this month and see if you still hit the issue.

That seems to be the issue.

How do i do that? Sorry, I'm still trying to figure out the difference between the Windows SDK, the .NET SDK, the Windows App SDK, the Windows Runtime, and everything else. And the fifteen different install methods 😂. Where do I upgrade?

If anyone knows... ^^

If anyone knows... ^^

Just update your visual studio to latest version.

[manodasanW]

As mentioned by the previous post, you can either update your Visual Studio version to the latest or update just the .NET SDK from here.
