2SXC DNN 缺少装配 System.Web.Helpers

Question

我们刚刚在 DNN 发行版上安装了 2sxc，无法创建基本内容。自定义应用程序加载没有问题，这只发生在内容应用程序中。

将内容模块添加到具有基本内容类型的空白页面会导致以下错误。这是在 DNN 9 和 .NET 4.8 上

Error: System.IO.FileLoadException: Could not load file or assembly 'System.Web.Helpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

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

事实证明，另一位团队成员更改了 web.config 以添加程序集，但将其放在了错误的位置：

错误：

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      /* ... */
    </assemblyBinding>
    <dependentAssembly>
      <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
    </dependentAssembly>
  </runtime>
</configuration>

已修复：

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      /* ... */
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>
