我编写了一个VSIX，在VS 2017中失败

System.IO.FileNotFoundException: Could not load file or assembly 'System.Numerics.Vectors, Version=4.1.4.0

然而，CSPROJ包含了该程序集的包

<PackageReference Include="System.Numerics.Vectors">
  <Version>4.5.0</Version>
</PackageReference>

并且我已经验证了System.Numerics.Vectors，Version=4.1.4.0位于extensions文件夹中：

C:\Users\IEUser\AppData\Local\Microsoft\VisualStudio\15.0_90a627f6\Extensions\j5lca0pj.xmg

我检查了fuslogvw并得到

*** Assembly Binder Log Entry  (4/6/2023 @ 9:19:29 AM) ***

虽然我直接包含了System.Numerics.Vectors包，但VSIX并不直接使用它，而是引用System.Memory，不确定这是否重要。
我还注意到，对于找到的其他包引用，fusion日志中的最后一行是在扩展文件夹中查找的，那么为什么不在那里查找Numerics.Vectors呢？
例

LOG: Attempting download of new URL file:///c:/users/ieuser/appdata/local/microsoft/visualstudio/15.0_90a627f6/extensions/j5lca0pj.xmg/GA4-NET.DLL.
LOG: Assembly download was successful. Attempting setup of file: c:\users\ieuser\appdata\local\microsoft\visualstudio\15.0_90a627f6\extensions\j5lca0pj.xmg\GA4-NET.dll

devenv.exe.config没有提到System.Numerics.Vectors，所以没有重定向。
