添加React.AspNet会导致app.UseMvc变得模棱两可

Question

我在VS2015中创建了一个新项目并选择了＃34; Web Application＆＃34;在＆＃34; ASP.NET 5预览模板＆＃34;

从NuGet添加React.AspNet后，项目无法构建，失败并出现以下错误。

Severity    Code    Description Project File    Line
Error   CS0121  The call is ambiguous between the following methods or      properties:    'Microsoft.AspNet.Builder.BuilderExtensions.UseMvc(Microsoft.AspNet.Builder.IApp licationBuilder, System.Action<Microsoft.AspNet.Routing.IRouteBuilder>)' and  'Microsoft.AspNet.Builder.MvcApplicationBuilderExtensions.UseMvc(Microsoft.AspNe t.Builder.IApplicationBuilder,  System.Action<Microsoft.AspNet.Routing.IRouteBuilder>)'  WebApplication3.DNX  4.5.1
C:\Users\UserName\Project\Startup.cs    127

Startup.cs - 这是模板默认的简化版本

using Microsoft.AspNet.Builder;

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {

        // Add MVC to the request pipeline.
        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });
    }

我的 Startup.cs 是否有问题，或者这是React.AspNet中的错误？
