Wix4 RC1: Strange Warnings when trying to detect Dotnet7 through netfx

[ChristianSauer]

I have adapted a WIP slightly to try and detect if Dotnet7 desktop is installed.

this gives a lot of warnings, which I am unable to understand:

Does anybody know the cause of this?

The warnings are trying to tell you that you're using something that isn't supported in a bundle. In v4, netfx:DotNetCompatibilityCheck is only implemented for MSI and netfx:DotNetCoreSearch is only implemented for bundles.
