[WiX V4] Why is DotNetCompatibilityCheckRef not allowed in Bundle?

[NJullienSweet]

As the title says, I'm wondering why you apparently only need to declare a DotNetCompatibilityCheck element in a Fragment for a bundle, but need DotNetCompatibilityCheckRef for a package. When I try to add a DotNetCompatibilityCheckRef in a Bundle, I get the following error line:

error WIX0005: The Bundle element contains an unexpected child element 'DotNetCompatibilityCheckRef'.

Am I missing something?

DotNetCompatibility check is only supported in MSIs and MSMs. You can see that in the documentation because of the allowed parents: https://wixtoolset.org/docs/schema/netfx/dotnetcompatibilitycheck/

DotNetCoreSdkSearch is only supported in Bundles. You can see that in the documentation because of the allowed parents: https://wixtoolset.org/docs/schema/netfx/dotnetcoresdksearch/
