CC @halter73 this is related to the work to bring up arm64 hosting bundle support - I'm working around it by temporarily disabling

aspnetcore/src/Installers/Windows/AspNetCoreModule-Setup/ANCMIISExpressV2/AncmIISExpressV2.wixproj

Lines 98 to 100 in 18b3b4a

	<Target Name="BeforeBuild" Condition="'$(Platform)' == 'arm64'">
	<MSBuild Projects="..\Forwarders\build.proj" />
	</Target>

in the VMR, but for Preview4 I'll probably move the Arm64 build of that project into Build Pass 2 (the issue is that we're trying to access x64 bits from an arm64 vertical, where they won't exist)
