Describe the bug

x86 web API app with COM object doesn't work when published as self contained app to folder with Asp.Net Core 3.1
My windows service API application was working correctly when my application was updated from Core 2.2 to 3.0 when published to folder but now it doesn't work when I updated to 3.1. Was the publish command for .netcore changed for 3.1?

To Reproduce

GitHub example repo here.

Create an Asp.Net Core Web API using the template.
Add a COM object
Set the first Property Group of the project to this:

 <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>
    <RuntimeIdentifier>win-x86</RuntimeIdentifier>
  </PropertyGroup>

Then publish as a self-contained x86 app to folder and try running the app in the folder.

When running the published project I get this.

C:\Daniel\Source\Repos\ServiceApi\ServiceApi\bin\Release\netcoreapp3.1\win-x86\publish>ServiceApi --console
Error:
  An assembly specified in the application dependencies manifest (ServiceApi.deps.json) was not found:
    package: 'Interop.Microsoft.Office.Core', version: '2.8.0.0'
    path: 'Interop.Microsoft.Office.Core.dll'

Thanks for contacting us. This looks like something more relevant to the dotnet/runtime repo. Moving this over there.

I reported this 7 days ago, see dotnet/sdk#3993

The fix is being tracked here dotnet/sdk#4038
