Question

我正在尝试将ASP.NET MVC项目部署到IIS 8.5.9600服务器。当我在VS 2015 pro中运行它时，一切都加载并运行得很好。当我发布它或手动加载它时，我得到以下错误页面：

Server Error in '/' Application.

Could not load file or assembly 'Microsoft.AspNet.Scaffolding.12.0' or one of its dependencies. An attempt was made to load a program with an incorrect format. 
  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

 Exception Details: System.BadImageFormatException: Could not load file or assembly 'Microsoft.AspNet.Scaffolding.12.0' or one of its dependencies. An attempt was made to load a program with an incorrect format.

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 'Microsoft.AspNet.Scaffolding.12.0' 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].

Answer 1

我们的一位管理员发现这是由于应用程序池不允许32位应用程序引起的。在“应用程序池”中，单击“高级设置”，将“启用32位应用程序”设置为True。

Answer 2

好的 - 所以我知道这是一年前发布的 - 但从查看此页面的人数（撰写本文时800强）来看，我认为这是一个需要更多澄清的问题。

我的应用程序在本地运行正常但是当部署到托管服务器时，我会收到此错误：https://i.stack.imgur.com/ANCu7.png

事实证明，默认情况下，任何本地IIS应用程序池都运行64位应用程序。您需要做的是更改该设置以32位运行您的应用程序。这就是我的结果：https://i.stack.imgur.com/DWxmY.png

您需要在本地计算机IIS上进行这些更改 - 然后将您的应用程序发布并部署到托管服务器。

有一篇非常有用的文章，我无法发布链接（因为目前我没有足够的信誉点发布3个链接）你可以通过谷歌搜索找到它：How to Enable a 32-bit Application Pool in IIS 7 (Dedicated/VPS) < / p>

Answer 3

我通过从我的网络项目中的Windows文件夹浏览中删除obj和bin文件夹来解决此问题。

重建项目后，文件夹和文件将再次重新生成，并且已修复。

Answer 4

所有先前的答案可能都是正确的。

但是

我有同样的错误。发现该程序集“ Microsoft.AspNet.Scaffolding.12.0”的加载已由IIS停止，因为该端口已被使用。

我通过更改应用程序的端口（端口已被使用）解决了该问题。

可能想在将IIS配置从64位更改为->服务器上的32位之前进行检查...

无法加载文件或程序集“Microsoft.AspNet.Scaffolding.12.0”
