【问题描述】：
我在以前工作的应用程序上用 RC 包更新了 ASP.NET 5 框架 beta-8 包。在我让它运行之后，在启动过程中发生了下一个错误：
InvalidOperationException：未配置身份验证处理程序来处理方案：自动 Microsoft.AspNet.Http.Authentication.Internal.DefaultAuthenticationManager.d__12.MoveNext()
var defaultPolicy =
new AuthorizationPolicyBuilder()
.RequireAuthenticatedUser()
.Build();
services.AddMvc(setup =>
{
setup.Filters.Add(new AuthorizeFilter(defaultPolicy)); // Error occurs here
});
如果有人有类似的问题，我会很感激你的想法或解决方案可能出了什么问题。对此异常的解释也值得赞赏。

【问题讨论】：
-
我刚刚开始使用 asp.net 进行最后一个测试版的开发（创建了一个新项目，然后对其进行了一些改进）并且在更新到 RC 后也遇到了问题，因为他们已经更改了各种 BASE-事物。不幸的是，我没有找到任何描述，如何更改现有项目以使其兼容。所以......然后我从新模板从头开始重新创建我的项目，以完全兼容。由于 MS 支持 RC 进行生产，我认为（希望如此）将来不会有这样的变化（2016 年第一季度发布版本）。
