Asp.net mvc 4部署错误

Question

我已经在mvc 4中开发了一个Web应用程序.在开发机器上一切都很好,但是在实时服务器上它给了我以下错误.

无法加载文件或程序集

'System.Web.Http,Version = 4.0.0.0,Culture = neutral,PublicKeyToken = 31bf3856ad364e35'或其依赖项之一.该模块应该包含一个程序集清单.

我尝试了以下解决方案:

• 将dll文件从本地驱动器复制到bin文件夹
• 检查我的主机是否启用了asp.net 4
• 已检查是否正确配置了web.config文件.

这是确切的屏幕跟踪.请注意,最后一行显示.net版本4以及asp.net版本4所以我认为它不是问题.请指导我.

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

我终于成功完成了它.希望它也能帮助那些有类似问题的人.

罪魁祸首是发布向导.我使用发布工具发布了我的项目.但是,当我上传已发布的项目时,它根本无法工作并显示system.web.http程序集已损坏.

我是怎么解决的 -

我从我项目的bin文件夹上传了system.web.http dll来覆盖发布向导的dll.

我被进一步提示进入其他dll,我为所有这些做了同样的事情.

一旦我用bin文件夹中的一个替换了所有错误的dll,应用程序就开始工作了.

我不确定它是否是Visual Studio发布向导的错误.如果有人对此问题有更好的了解,请在此处发帖寻求他人的帮助.
