Hello Team


We are building an installer (msi) and patch (msp). When I opened the MSI
and MSP using the Orca tool, I can see the following two binaries being
reported in the package




However, I am unable to see these in the WIX NuGet path I am using. 


Does anyone know where these binaries are coming from? And is there a
possibility to use these DLLs from a custom path before the compilation? The
reason is that we would like to sign these DLLs with a specific signing


Appreciate the help.
