VSIX无法从包含的软件包中找到引用的程序集，VS 2017。

c#asp.netvsixvspackage
3

我编写了一个在VS 2017中失败的VSIX

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

然而，csproj包含了该程序集的软件包

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

我已经验证了System.Numerics.Vectors，Version=4.1.4.0落在扩展文件夹中：

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

我检查了 fuslogvw 并获得了以下结果

虽然我直接包含了System.Numerics.Vectors包，但它并没有被VSIX直接使用，而是System.Memory的一个引用，不确定这是否有影响。

我还注意到对于其他找到的包引用，融合日志的最后一行是在扩展文件夹中查找，那么为什么它不在那里查找Numerics.Vectors呢？

例如：

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 中没有提到 System.Numerics.Vectors，因此没有重定向。

更新：我发现通过删除这些绑定重定向并将包引用从5降级到4.5的方式，问题已经消失了。

 [assembly: Microsoft.VisualStudio.Shell.ProvideBindingRedirection(AssemblyName = "System.Memory", OldVersionLowerBound = "1.0.0.0", OldVersionUpperBound = "4.0.1.1", NewVersion = "4.0.1.2")]
 [assembly: Microsoft.VisualStudio.Shell.ProvideBindingRedirection(AssemblyName = "System.Runtime.CompilerServices.Unsafe", OldVersionLowerBound = "1.0.0.0", OldVersionUpperBound = "4.0.4.9", NewVersion = "5.0.0.0")]
 [assembly: Microsoft.VisualStudio.Shell.ProvideBindingRedirection(AssemblyName = "System.Numerics.Vectors", OldVersionLowerBound = "1.0.0.0", OldVersionUpperBound = "4.1.3.0", NewVersion = "4.1.4.0")]

在这个过程中，我发现当我删除重定向到System.Numerics.Vectors时，它就不再抱怨找不到它了，而是抱怨找不到System.Memory。还有一个引用System.Memory -> System.Numerics.Vectors。我还没有时间仔细思考，但很明显重定向会影响它如何查找程序集。我已经度过了这个难关。

错误提示无法找到程序集 System.Numerics.Vectors 的版本 4.1.4.0，而您已经安装/引用了版本 4.5.4.0。
您需要在 web.config 中添加程序集绑定重定向。
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Numerics.Vectors" publicKeyToken="B03F5F7F11D50A3A" culture="neutral"/>
        <bindingRedirect oldVersion="0.0.0.0-4.5.4.0" newVersion="4.5.4.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>
“4.5.4”是软件包版本，其中包含程序集版本“4.1.4.0”，所以我的做法是正确的，并且我已经验证“4.1.4.0”与我的VSIX文件在同一个文件夹中。 - Jim W says reinstate Monica

我相信我已经弄清楚了。

（至少在VSIX的上下文中，也许是一般情况下）假设您有对程序集A v1的引用，该程序集引用了B v1。

MyProj -> A v1 -> B v1

但无论出于何种原因，您需要将A重定向到v2，并且

A v2 -> B v2

所以你在项目中放置了一个绑定重定向A v1 to A v2。即使B v2与您的项目一起分发，似乎程序集绑定器会失去上下文，并且不会在与MyProj相同的目录中查找B v2 - 而没有重定向时它会在MyProj目录中查找。
