在一个.NET 7项目中，我使用Serilog（最新的Serilog.Extensions.Logging.File v3.0.0），并在尝试使用dotnet publish编译项目时得到一系列错误NU1605：

Agent.csproj : error NU1605: Detected package downgrade: System.IO from 4.3.0 to 4.1.0. Reference the package directly from the project to select a different version.

经过深入研究，我发现在.csproj文件中添加以下内容可以解决这个问题：

<PackageReference Include="Microsoft.NETCore.Platforms" Version="7.0.0" />
    <PackageReference Include="Microsoft.NETCore.Targets" Version="5.0.0" PrivateAssets="All" />

但是，Microsoft.NETCore.Targets软件包在v6.0.0-preview.4.21253.7停止更新。显然，它已经被弃用，请参阅"Delete Microsoft.NETCore.Targets package"问题。
为了进一步排除故障，我启用了"repeatable package restores using a lock file"（无论如何，这是CI构建的正确做法）。

鉴于Microsoft.NETCore.Targets已被弃用，解决此问题的正确策略是什么？我相信，现在.NET 3.x LTS已接近EOL，而且.NET已发布，解决此问题的策略可能相当普遍。
此外，假设Microsoft.NETCore.Targets基本上只是一个空包，其中包含一个零长度的lib\netstandard1.0\_._文件，那么当前的解决方案背后的魔力是什么？
