asp.net-mvc - Asp.net mvc 4 部署错误

Question

我在 mvc 4 中开发了一个 web 应用程序。在开发机器上一切正常，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' or one of its dependencies. The module was expected to contain an assembly manifest.

我尝试了以下解决方案:

将 dll 文件从我的本地驱动器复制到 bin 文件夹

检查我的主机是否启用了 asp.net 4

已检查 web.config 文件是否已正确配置。

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

Answer 1

我终于设法完成了。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——

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

我被进一步提示输入其他 dll，我对所有这些 dll 都做了同样的事情。

一旦我用我的 bin 文件夹中的一个替换了所有错误的 dll，该应用程序就开始工作。

我不确定这是否是 Visual Studio 发布向导的错误。如果有人对此问题有更好的想法，请在此处发布以帮助他人。
