I have already remove all references from DotNetOpenAuth with packager manager. Also I checked by my self references for every Auth assembly I had in my project and there is none.

我已经使用打包管理器从 DotNetOpenAuth 中删除了所有引用。我还通过我的自我引用检查了我项目中的每个 Auth 程序集，但没有。

This is my packages.config

If you don't want use OAuth, remove references: both the WebPages OAuth DLL (I think it's Microsoft.Web.WebPages.OAuth.dll¹) and DotNetOpenAuth DLLs.

如果您不想使用 OAuth，请删除引用：WebPages OAuth DLL（我认为是Microsoft.Web.WebPages.OAuth.dll ¹）和 DotNetOpenAuth DLL。

¹: You can find the filename in Calling assembly. So, removing all calling assemblyof DotNetOpenAuth.Coreshould work for you. This approach should work for other unused missing references.

¹：您可以在Calling assembly. 因此，删除所有calling assembly内容DotNetOpenAuth.Core应该对您有用。这种方法应该适用于其他未使用的缺失引用。

Try doing a global solution search (ctrl+shift+f if you haven't changed it) for the value '2780ccd10d57b246'. I'm guessing you'll find it in your web.config.

尝试对值 '2780ccd10d57b246' 进行全局解决方案搜索（如果您尚未更改，请按 ctrl+shift+f）。我猜你会在你的 web.config 中找到它。

I've seen this happen when deploying an MVC application as bin deploy. When you right-click on a project and select Add deployable dependenciesVS will add the references to Oauth if you check the box next to ASP .NET Webpages with Razor syntax.

我在将 MVC 应用程序部署为bin deploy. 当您右键单击一个项目并选择Add deployable dependenciesVS 时，如果您选中旁边的框，VS 将添加对 Oauth 的引用ASP .NET Webpages with Razor syntax。

To fix this, delete the _bin_deployableAssembliesfolder, and your application's binfolder and then clean and rebuild your application and it will work again.

要解决此问题，请删除该_bin_deployableAssemblies文件夹和您的应用程序bin文件夹，然后清理并重建您的应用程序，它会再次运行。

I had similar problem. It was really strange as the project was running OK a day before.

我有类似的问题。这真的很奇怪，因为该项目前一天运行正常。

Removing obj and bin folders from the project folder, cleaning the solution and rebuilding it worked.

从项目文件夹中删除 obj 和 bin 文件夹，清理解决方案并重建它。

Hope that helps.

希望有帮助。

Remove any Microsoft.Web.WebPages.OAuth dependencies everywhere in your projects.

删除项目中随处可见的任何 Microsoft.Web.WebPages.OAuth 依赖项。

In my case the MVC4 application was running fine in the VS2012 debugger, but I was getting the "Could not load file or assembly 'DotNetOpenAuth.Core'" error when I publish the application on the server.

在我的例子中，MVC4 应用程序在 VS2012 调试器中运行良好，但是当我在服务器上发布应用程序时出现“无法加载文件或程序集‘DotNetOpenAuth.Core’”错误。

Checking the "Delete all existing files prior to publish" checkbox on the settings tab of Publish Web window solved the issue.

选中发布 Web 窗口设置选项卡上的“发布前删除所有现有文件”复选框解决了该问题。

I solved the problem by installing the package using Nuget

One more solution option is to have assembly dependency as follows:

另一种解决方案选项是具有程序集依赖性，如下所示：

<dependentAssembly>
  <assemblyIdentity name="DotNetOpenAuth.AspNet"
                    publicKeyToken="2780ccd10d57b246"
                    culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-4.3.0.0" newVersion="4.3.0.0" />
</dependentAssembly>
<dependentAssembly>
  <assemblyIdentity name="DotNetOpenAuth.Core"
                    publicKeyToken="2780ccd10d57b246"
                    culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-4.3.0.0" newVersion="4.3.0.0" />
</dependentAssembly>

In case this helps anyone - I was unable to uninstall the DotNetOpenAuth components through Nuget, so I resolved this error by deleting them from the references list directly and then re-installing dotnetopenauth through nuget.

如果这对任何人有帮助 - 我无法通过 Nuget 卸载 DotNetOpenAuth 组件，因此我通过直接从参考列表中删除它们然后通过 nuget 重新安装 dotnetopenauth 来解决此错误。
