AddAuthorizationへの呼び出しはあいまいです

Question

今日まで働いていた簡単なポリシーがいくつかありますが、私はそれらを壊すために何もしなかったと確信しています。

The call is ambiguous between the following methods or properties: 'Microsoft.Extensions.DependencyInjection.AuthorizationServiceCollectionExtensions.AddAuthorization(Microsoft.Extensions.DependencyInjection.IServiceCollection, System.Action)' and 'Microsoft.Extensions.DependencyInjection.AuthorizationServiceCollectionExtensions.AddAuthorization(Microsoft.Extensions.DependencyInjection.IServiceCollection, System.Action)'

私は最近、リコールすることができません：それは私のAddAuthorization機能のために、このエラーが発生します

services.AddAuthorization(options => 
     { 
      options.AddPolicy("AboveUser", 
       policy => policy.RequireRole("Admin", "Manager")); 
      options.AddPolicy("IsAdmin", 
       policy => policy.RequireRole("Admin")); 
      options.AddPolicy("IsManager", 
       policy => policy.RequireRole("Manager")); 
     }); 

：Startup.csでは、ConfigureServicesでは、これはエラーを投げているコードです私のproject.jsonまたはそのようなものに変更するが、それは場合に役立ちます私はここでそれを参照します：

どれ支援がいただければ幸いです

beta/rcバージョンとRTMを混在させないでください！

"Microsoft.AspNet.Mvc.Core": "6.0.0-*", 

それは私が目の余分なペアを必要と推測し、

"Microsoft.AspNetCore.Mvc.Core": "1.1.0",
