Question

有一些简单的政策，直到今天一直在努力，我很确定我没有做任何事情来打破它们。在Startup.cs中，在ConfigureServices中，这是抛出错误的代码：

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"));
        });

它为AddAuthorization函数提供了这个错误：

以下方法或属性之间的调用不明确：'Microsoft.Extensions.DependencyInjection.AuthorizationServiceCollectionExtensions.AddAuthorization（Microsoft.Extensions.DependencyInjection.IServiceCollection，System.Action）'和'Microsoft.Extensions.DependencyInjection.AuthorizationServiceCollectionExtensions.AddAuthorization（ Microsoft.Extensions.DependencyInjection.IServiceCollection，System.Action）'

我记不起最近对我的project.json或类似的东西进行了更改，但如果有帮助我会在这里引用它：

不要将beta / rc版本与RTM混合!!!

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

它＆＃39; S

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

调用AddAuthorization是不明确的
