A ticket was opened here last year and a workaround has been provided:

and then in bundle.wxs you need to add this:

  <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">

  <Bundle Name="..."
          Version="..." 
          Manufacturer="..." 
          UpgradeCode="..." 
          >

    <Chain>      

      <!--Install .Net Framework 4.7.1-->
      <PackageGroupRef Id="NetFx471Redist"/>

      <!--Install Product-->
      <MsiPackage
        Id="Setup"   
        DisplayInternalUI="yes"
        Compressed="yes"
        SourceFile="..."
        Vital="yes">        
      </MsiPackage>     

    </Chain>
  </Bundle>  
</Wix>

I found it bit misleading that the question is about 4.7.2 but the accepted answer about 4.7.1 version.

All the exact bits are here.

Just tested on a computer without 4.7.2 installed and all worked perfectly - the installer downloaded and installed .NET Framework component and first then it continued with the program installation itself.
