Questions about adding WinUI 3 C++ project to Visual Studio installer setup project

[amtopel]

I have an unpackaged WinUI C++ .exe project, which I created using the WinUI 3 blank template. I also have a setup/installer project, which I created using the Visual Studio Installer Projects 2022 extension. I've now added the WinUI project output to the installer project, but I've had a couple issues come up.

First of all, the installer project says that the .NET Framework is a necessary launch condition. So when the installer runs, it shows a prompt to download the .NET Framework. Is that correct? Does an unpackaged WinUI C++ application require .NET to run?

And second, when building the installer project, I get a series of these warnings:
