.NET6中runtimeconfig.json的additionalProbingPaths致框架DLL探测异常求助

我正在将一个包含大量DLL的项目从.NET Framework迁移至.NET 6，迁移工作已完成，但部署环节遇到瓶颈：我们希望将所有第三方DLL放置在子文件夹（通常命名为lib）中，这种部署方式在.NET Framework中可正常运行，但在.NET 6下无法沿用。

我们尝试使用.runtimeconfig.json文件中的additionalProbingPaths配置项作为替代方案，但遇到两个关键问题：

• 无法直接将DLL复制到目标子文件夹使其生效，必须创建与NuGet包一致的复杂目录结构；该问题可通过编辑.deps.json文件解决，让所有DLL集中到指定文件夹。
• 设置additionalProbingPaths后，程序似乎会针对**所有DLL（包括框架自带DLL）**仅在配置的路径中搜索，而非仅针对第三方包，最终导致框架DLL加载失败。
