Interop.Microsoft.Office.*.dll missing on publish

_This issue has been moved from [a ticket on Developer Community](https://developercommunity2.visualstudio.com/t/InteropMicrosoft-missing-on-publish/1108259)._

---
I am using Visual Studio Enterprise 2019 16.6.3.
In a .NET Core 3.1 WPF solution there are libraries that use MS Office COM references. When I publish a WPF application via FolderProfile that references such a library, the Interop.Microsoft.Office.*.dll is missing in the publish directory. However, it is available in the build directory of the library.
I have attached a small example. Just call
msbuild Exe\Exe.csproj /t:restore /t:publish /p:Configuration=Release /p:Platform=x64 /p:PublishProfile=FolderProfile

Thank you for taking the time to log this issue! Did you still reproduce this issue in the latest stable version of Visual Studio installed from https://visualstudio.microsoft.com/downloads ?

If so, in order for us to investigate this further, could you please provide repro steps, a more detailed description of the faulty behavior and the actions you were taking when the issue appeared to help us better understand this scenario?

We look forward to hearing from you!

I added a replicate example a long time ago. So it can be reproduced.

In the meantime, in cooperation with another Microsoft employee, we have come to the conclusion that the Interop Dlls are not required in the delivery in order to run correctly.
