C# Office 365应用程序创建错误：引发了类型为“Microsoft.Office365.OAuth.MissingConfigurationValueException”的异常

我在VS 2013中开发了一款Office 365应用程序。通过连接的服务，我连接到了我的O365帐户。但代码在以下行中失败：

 _discoveryContext = await DiscoveryContext.CreateAsync();

我得到的例外情况如下：

Exception of type 'Microsoft.Office365.OAuth.MissingConfigurationValueException' was thrown. 
  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: Microsoft.Office365.OAuth.MissingConfigurationValueException: Exception of type 'Microsoft.Office365.OAuth.MissingConfigurationValueException' was thrown.

听起来好像连接的服务向导以某种方式失败了。检查您的Web.config文件。它在appSettings下应具有以下键：

如果它们丢失，您可能需要重新添加已连接的服务。

谢谢。但这些部分是存在的。我有3把钥匙。我们是否需要在AD中进行额外的手动配置？表示在Azure Active Directory中注册。根据我的理解，VS 2013开展了这项活动。
