c# - 带有 vNext 的 SignalR

Question

我很难在 vNext 项目(epmty 模板)中使用 SignalR。

首先，我将 SignalR.Server 依赖项添加到我的 project.json 文件中，它现在看起来像这样:

{
    "webroot": ".",
    "dependencies": {
        "Microsoft.AspNet.Server.IIS": "1.0.0-beta3",
        "Microsoft.AspNet.Server.WebListener": "1.0.0-*",
        "Microsoft.AspNet.StaticFiles": "1.0.0-*",
        "Microsoft.AspNet.SignalR.Server": "3.0.0-*",
        "Serilog": "1.4.113.0"
},
    "commands": {
        "web": "Microsoft.AspNet.Hosting server=Microsoft.AspNet.Server.WebListener server.urls=http://localhost:5002"
    },
    "frameworks": {
        "dnx451": {
            "dependencies": {
                "Microsoft.Framework.Logging.Serilog": "1.0.0-*"
            }
        },
        "dnxcore50": { }
    }
}

然后我想在我的 Startup.cs 中映射 SignalR(因为我在 git 的某个地方找到了)

 public void ConfigureServices(IServiceCollection services)
    {
        services.AddSignalR(options =>
        {
            options.Hubs.EnableDetailedErrors = true;
        });
    }

    public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
    {
#if DNX451
        string OutputTemplate = "{SourceContext} {Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] {Message}{NewLine}{Exception}";

        var serilog = new LoggerConfiguration()
            .MinimumLevel.Verbose()
            .WriteTo.RollingFile(@".\SignalR-Log-{Date}.txt", outputTemplate: OutputTemplate);

        loggerFactory.AddSerilog(serilog);
#endif

        app.UseFileServer();

        app.UseSignalR<RawConnection>("/raw-connection");
        app.UseSignalR();
    }

，但是当我在顶部添加时:

using Microsoft.AspNet.SignalR;

我得到错误:

The type or namespace name 'SignalR' does not exist in the namespace >'Microsoft.AspNet' (are you missing an assembly reference?) VersaWeb.ASP.NET >5.0 c:\Users\Jakub\documents\visual studio >2015\Projects\VersaWeb\src\VersaWeb\Startup.cs

我现在卡住了。

编辑:

问题一定出在 project.json 上，因为当我从音乐商店复制一个时，问题就消失了。

这是我当前的 project.json(可能不需要一些依赖项，所以我要进一步测试它)

Answer 1

结帐 MusicStore sample ，它使用 SignalR。我也在我的 vnext 项目中使用 SignalR(尽管使用的是 kre，而不是新的 dnx 东西)，所以它绝对可行。
