c# - AspNetCompiler - 尝试加载格式不正确的程序

Question

我正在构建一个仅 64 位的 Web 应用程序 (AssemblyA) 并引用我构建的另一个应用程序，该应用程序也是仅 64 位的 (AssemblyB)。

当我将 AssemblyB 添加为 AssemblyA 中的引用时，我在 Visual Studio 中收到以下编译错误:

ASPNETCOMPILER Could not load file or assembly 'AssemblyB' or one of its dependencies. An attempt was made to load a program with an incorrect format.

我的应用程序的两个平台目标设置都设置为 x64，两个目标框架设置都是 .Net Framework 4.6 并且 Prefer 32bit 未选中 .

我尝试在 AssemblyA 中引用 AssemblyB 的每个依赖引用，确保所有依赖引用的版本都相同。

我用过这个问题:How to determine if a .NET assembly was built for x86 or x64?确认所有引用的程序集都是 MSIL 或 AMD64。

我使用了启用了 errorstack 选项的 aspnet_compiler.exe 命令行工具并获得了以下堆栈跟踪:

[BadImageFormatException]: Could not load file or assembly 'AssemblyB' or one of its dependencies. An attempt was made to load a program with an incorrect format.

我查看了以下相关问题，但没有人回答这个问题。大多数与 IIS 配置有关，但不是这种情况，因为这是编译错误，或者有解决方案，如将项目设置为允许 32 位平台目标，这不适合我的情况:

• "An attempt was made to load a program with an incorrect format" even when the platforms are the same (不如使用 IIS 配置好)
• Could not load file or assembly ... An attempt was made to load a program with an incorrect format (System.BadImageFormatException) (运行时错误不好)
• System.BadImageFormatException An attempt was made to load a program with an incorrect format (不如使用 32 位解决方案)
• Could not load file or assembly 'xxx' or one of its dependencies. An attempt was made to load a program with an incorrect format (不如使用 32 位解决方案)

我不知道从这里去哪里。重申一下，我不想将我的任何一个项目设置为 32 位，这不是 IIS 配置的问题，因为这是一个编译错误。

我还在几台不同的机器和全新的应用程序上尝试过，结果相同。

如何修复此编译错误？

指令<AspNetCompiler />接受争论ToolPath可以定向到 64 位版本的 aspnet_compiler.exe .这在 this blogpost 中有描述。 .它的要点是，编辑您的 csproj 文件:

添加 ToolPath属性为 AspNetCompiler节点:

<AspNetCompiler VirtualPath="temp" PhysicalPath="$(ProjectDir)" ToolPath="$(AspNetToolPath)" />

哪里MvcBuildViews已定义，添加属性 FrameworkVersion和 AspNetToolPath ，像这样:

<MvcBuildViews>true</MvcBuildViews>
<FrameworkVersion>v4.0.30319</FrameworkVersion>
<AspNetToolPath Condition=" '$(Platform)' == 'x64'">$(windir)\Microsoft.NET\Framework64\$(FrameworkVersion)</AspNetToolPath>
