依赖Asp.net Core的类库

用Visual Studio创建的类库想依赖Asp.net Core的某些组件，比如Microsoft.AspNetCore.Mvc.Core，在.netcore 3.1之后不再单独提供nuget包，应该怎么办呢？直接在.csproj文件里面添加FrameworkReference：

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

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>

</Project>
