VSIX 无法从包含的包中找到引用的程序集，VS 2017

Question

我写了一个在 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 包含该程序集的包

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

我已经验证 System.Numerics.Vectors, Version=4.1.4.0 位于扩展文件夹中：

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

我检查了

fuslogvw

并得到

虽然我直接包含了 System.Numerics.Vectors 包，但它没有被 VSIX 直接使用，而是 System.Memory 的引用，不确定这是否重要。

我还注意到，对于找到的其他包引用，融合日志中的最后一行是在扩展文件夹中查找，那么为什么不在那里查找 Numerics.Vectors？

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

没有提到 System.Numerics.Vectors，所以没有重定向。

更新：我发现通过删除这些绑定重定向并将我对

System.Runtime.CompilerServices.Unsafe

的包引用从 5 降级到 4.5，问题已经消失。

 [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，我发现当我删除到

System.Numerics.Vectors

的重定向时，它不再抱怨找不到那个，而是抱怨找不到

System.Memory

。还有一个参考，

System.Memory -> System.Numerics.Vectors

。我还没有时间真正考虑它，但显然重定向正在影响它如何找到程序集。我现在已经过去了。

Answer 1

错误指出它无法找到程序集 System.Numerics.Vectors 的版本 4.1.4.0 并且您已经安装/引用版本 4.5.4.0.

您需要将程序集绑定重定向添加到您的 web.config。

<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>

Answer 2

我相信我已经弄明白了。

（至少在 VSIX 的上下文中，也许是一般情况下）假设您引用了程序集 A v1，它引用了 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

所以你在你的项目中放置了一个绑定 redir

A v1 to A v2

。即使 B v2 与您的项目一起分发，程序集活页夹似乎会丢失上下文并且不会在与 MyProj 所在的同一目录中查找 B v2 - 而如果没有重定向，它会在 MyProj 目录中查找。
