Question

我正在尝试使用ASP.NET MVC 3中的Facebook程序集。我正在学习本教程：http://csharpsdk.org/docs/web/getting-started 但是当我试图使用他的一个功能时......

[FacebookAuthorize(LoginUrl = "...")]
    public abstract class SuperController<T> : Controller where T : BaseRequirement
{
...
}

当其他控制器继承它时，我得到一个例外。例外：

Could not load type 'Facebook.FacebookApplication' from assembly 'Facebook, Version=6.0.10.0, Culture=neutral, PublicKeyToken=58cb4f2111d1e6de'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.TypeLoadException: Could not load type 'Facebook.FacebookApplication' from assembly 'Facebook, Version=6.0.10.0, Culture=neutral, PublicKeyToken=58cb4f2111d1e6de'.

Source Error:

我尝试从Nuget更新并检查我是否使用上一版本，我认为没问题。在我的app.config中，我发现了这个：

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="Facebook" publicKeyToken="58cb4f2111d1e6de" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-6.0.10.0" newVersion="6.0.10.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

提前致谢，

FacebookAuthorize已在v6中删除。

您可以在https://github.com/facebook-csharp-sdk/facebook-aspnet-sample和https://github.com/facebook-csharp-sdk/facebook-canvas-aspnet-sample

找到v6样本
