无法在ASP.NET Webforms站点中加载文件或程序集'System.Web.WebPages.Deployment或其依赖项错误之一

Question

我有一个ASP.NET WebForms应用程序，最近已将其升级到使用VS2013的.NET 4.0。 它最初是在VS2010中构建的。 它还使用DevExpress控件版本16.2

当我尝试构建站点时，出现以下错误：-

    Error   1   Could not load file or assembly 'System.Web.WebPages.Deployment,            Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

通过在ASP.NET MVC中将依赖程序集引用添加到Web.config文件中，我已经看到了针对第一个错误的修复程序，但这似乎不起作用。

我也不知道为什么不能引用诸如collection和EventArgs之类的东西。

有任何想法吗？

Answer 1

“该系统找不到指定的文件。” -您的路线是错误的。 您也可以检查特定的版本设置。 如果将reg值[HKLM \\ Software \\ Microsoft \\ Fusion！EnableLog]（DWORD）设置为1，则可以看到绑定路径。

Answer 2

弄清楚了。 我不得不补充：-

<runtime>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.WebPages.Deployment" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

到web.config文件

和

将DLL放入bin文件夹中，以使应用程序正确构建。
