突然间，我的网站没有加载并给我以下错误。我在Windows 10 Home上使用.Net Framework 4.7.1运行VS2017。

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

有什么建议吗？

Answer 1

对我有用的是删除我的网络应用程序下的bin和obj目录，然后重建。

Answer 2

这里的派对有点晚了，但是there's a known issue with .NET Framework 4.7.1 in this regard。据说按4.7.2排序，但与此同时你能做什么？

该问题与序列化程序集有关，您可以选择将其设置为生成或不作为构建的一部分（rclick项目 - ＆gt;属性 - ＆gt;构建选项卡 - ＆gt;请参阅底部的'生成序列化程序集'。）

对我有用的 - 我站在其他部分的肩膀上 - 是为了确保此设置设置为'自动'。做一个完整的“干净解决方案”，另外如果偏执，这个PowerShell代码段如果在您的解决方案根文件夹中运行则很方便：

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中（仅在封闭的<Project>标记内：

<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，请明确将“生成序列化程序集”设置为“打开”以强制生成，并重建＆amp;运行

Answer 3

今天我安装了Acumatica 2018 R1，我遇到过这个问题。从bin文件夹中删除System.IO.Compression.ZipFile修复了问题。

Answer 4

我也多次遇到此问题，此错误可能是由于在bin文件夹中引用或加载dll引起的。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

除了创建新实例并迁移所有自定义外，没有解决方案。这些错误只是随机的，很难追查或解决。

Answer 6

我对此错误进行了研究

从错误中我们可以看到，当我们在Aspnetcore项目中引用基于SOAP的项目时，我们不能直接使用它们。这是由于平台Aspnetcore的实现。

可以使用reflection加载它。但是，它允许我们动态使用内部类型。可能会在Aspnetcore的更高版本中释放对licenced肥皂装配等的支持。

当dll版本不同于X86或64等时，删除bin文件夹等是一个解决方案。真正的问题是SOAP协议，WebSocket，Proxy等实现。它们不能直接与Aspnetcore项目一起使用。 github中有patch个项目为此

无法加载引用程序集以供执行
