无法加载参考组件进行执行

Question

突然间，我的网站没有加载，给我以下错误。我正在Windows 10 Home上使用.NET Framework 4.7.1运行VS2017。

[BadImageFormatException: Cannot load a reference assembly for execution.]

有什么建议？

Answer 1

对我有用的是在我的Web应用下删除bin和obj目录，然后重建。

Answer 2

在这方面存在.NET Framework 4.7.1的已知问题。据说在4.7.2中排序，但与此同时，您该怎么办？

该问题与序列化组件有关，您可以选择将其设置为生成或不作为构建的一部分(rclick project-> properties-> build tab-> ward of tocare of tocare''。P>

对我有用的东西 - 我站在这里的其他人肩上 - 是为了确保将此设置设置为"自动"。做一个完整的"干净解决方案"，此外，如果在解决方案的根文件夹中运行，则此PowerShell片段很方便：

Get-ChildItem . -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }

接下来，将以下目标添加到您的CSPROJ(仅在封闭的<Project>标签中：

<Target Name="RemoveDesignTimeFacadesBeforeSGen" BeforeTargets="GenerateSerializationAssemblies">
    <ItemGroup>
      <ReferencePath Remove="@(_DesignTimeFacadeAssemblies_Names->'%(OriginalIdentity)')" />
    </ItemGroup>
    <Message Importance="normal" Text="Removing DesignTimeFacades from ReferencePath before running SGen." />
  </Target>
  <Target Name="ReAddDesignTimeFacadesBeforeSGen" AfterTargets="GenerateSerializationAssemblies">
    <ItemGroup>
      <ReferencePath Include="@(_DesignTimeFacadeAssemblies_Names->'%(OriginalIdentity)')" />
    </ItemGroup>
    <Message Importance="normal" Text="Adding back DesignTimeFacades from ReferencePath now that SGen has run." />
  </Target>

如果仍然没有运气，则明确将"生成序列化组件"设置为" on"，以强迫生成，然后重建＆amp;运行。

Answer 3

今天我已经安装了Acumatica 2018 R1，并且遇到了这个问题。emoving system.io.compression.pression.zipfile从bin文件夹解决了问题。

Answer 4

我也多次遇到此问题，此错误可能会通过在您的bin文件夹中的引用或加载问题引起。只需删除.bin文件夹并重建您的应用程序即可。

快乐的编码。

Answer 5

我对错误有一些研究

从错误中可以看到，当我们参考ASPNETCORE项目中的基于肥皂的项目时，我们不能直接使用它们。这是由于实现了平台AspnetCore。

可以使用反射加载。但是，它允许我们动态使用内部类型。支持可以在以后的Aspnetcore版本中发布，用于许可肥皂组件等。

删除bin文件夹等是当DLL版本不同的x86或64等。真正的问题是SOAP协议，WebSocket，代理等实现。它们不能直接与Aspnetcore项目一起使用。在GitHub中有补丁项目

Answer 6

我在从4.6.2升级到4.8时遇到了这个问题。

修复：

1. 从web.config删除汇编重定向
2. 重建项目
3. 双击组件绑定在VS中的绑定警告，以重新生成必要的重定向
4. 没有警告的重建

Answer 7

我删除了启动项目的bin和obj文件夹。然后重建解决方案。它起作用。

Answer 8

在所有删除NBIN文件夹/OBJ文件夹/清洁/重建之后：无效。错误清楚地告诉您有关问题的组件。转到您的web.config文件并找到该组件。删除并重新引用

Answer 9

我从.NET Framework 4.6.2到4.8迁移后遇到了相同的问题，并且推荐的修复程序都不适合我，直到我将项目更新为最新的.NET Framework 4.8.1。我继续删除bin文件夹，然后开始再次工作
