PackExcelAddIn error DNA-818471385 #700

After updating to the latest version of visual studio (17.10.2) I started getting the error below on build.

1>MSBUILD : PackExcelAddIn error DNA-818471385: Assembly at bin\Debug\net6.0-windows\System.Threading.Channels.dll could not be packed. Possibly a mixed assembly? (These are not supported yet.)

I am able to reproduce this with this minimal project file (no code needed)

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net6.0-windows</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>    
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="ExcelDna.AddIn" Version="1.8.0" />
    <PackageReference Include="System.Threading.Channels" Version="7.0.0" />
  </ItemGroup>

</Project>

The error only happens when building with-in visual studio, not when building via dotnet build.

@Sergey-Vlasov Could you confirm this problem, and maybe track down what the problem is with the System.Threading.Channels package?
