Microsoft.EntityFrameworkCore.Design 10 RC2 adds BuildHost directories to solution explorer

[andrewbabbittdev]

Bug description

BuildHost-net472 & BuildHost-netcore directories are showing up in the solution explorer as of RC2 in both VSCode and Visual Studio

Your code

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net10.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="10.0.0-rc.2.25502.107">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

</Project>

Does not happen with RC1, can be negated by removing contentfiles from IncludeAssets but this is also the default when installing the package.
