Visual Studio MVC平台 - x86和x64？

Question

我们有一个非常烦人的问题，大约一个月前开始，我们可以在一个需要自动代码生成/脚手架的MVC项目中添加一个控制器。

我们今天发现它与平台有关。最初，它设置为任何CPU，对我来说似乎是正确的设置。但是，我们将其设置为x86，因为我们的Visual Studio版本是32位，我们可以再次添加控制器。添加了一个构建的控制器，然后去查看应用程序，它出现以下错误：

无法加载文件或程序集“仪表板”或其某个依赖项。尝试加载格式不正确的程序。   描述：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源自代码的位置的更多信息。

异常详细信息：System.BadImageFormatException：无法加载文件或程序集“仪表板”或其某个依赖项。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].



Stack Trace:

   System.Web.HttpRuntime.EnsureFirstRequestInit(HttpContext context) +159
   System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +12441597

然后我们需要将它设置为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？它开始时已经开始了，我们并不想真正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？

如果您在IIS上运行该站点，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，则需要为应用程序池启用它。
