Visual Studio MVC 平台 - x86 和 x64？
Visual Studio MVC Platforms - x86 and x64?
大约一个月前我们遇到了一个非常烦人的问题，我们可以在需要自动代码的 MVC 项目中添加一个控制器 generation/scaffolding。
我们今天发现它与平台有关。最初，它被设置为 Any CPU，这对我来说似乎是正确的设置。但是，我们将其设置为 x86，因为我们拥有的 Visual Studio 版本是 32 位，并且我们能够再次添加控制器。添加了一个控制器，构建，然后去查看应用程序，它给出了以下错误：
无法加载文件或程序集 'Dashboard' 或其依赖项之一。试图加载格式不正确的程序。
说明：在执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其在代码中的来源的更多信息。
异常详细信息：System.BadImageFormatException：无法加载文件或程序集 'Dashboard' 或其依赖项之一。试图加载格式不正确的程序。
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Assembly Load Trace: The following information can be helpful to determine why the assembly 'Dashboard' could not be loaded.
WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

然后我们需要将其设置为 x64 或 Any CPU 以在浏览器中查看项目，但它会阻止我们再次添加控制器。
有谁知道我们应该使用什么设置？它是突然开始的，我们真的不想根据我们正在做的事情在平台之间进行交换和更改，因为它确实应该在任何 CPU 上运行吗？
如果您是 运行 IIS 上的站点，那么这可能就是您所缺少的：
如果您的应用程序是为 x86 构建的，则需要为您的应用程序池启用它。
