Question

我有asp.net项目。我想用signalR类创建聊天室。首先，我安装了Package和nugget但是我无法在新项目Field中看到Signal hub Classes。我的安装消息来自package =＆gt;

                Install-Package Microsoft.AspNet.SignalR
                The source at nuget.org [https://www.nuget.org/api/v2/] is unreachable.     
                 Falling back to NuGet Local Cache at  
                C:\Users\sali\AppData\Local\NuGet\Cache

                  'Microsoft.AspNet.SignalR 2.0.3' already installed.
                 Prsonal already has a reference to 'Microsoft.AspNet.SignalR 2.0.3'.

什么问题？

Answer 1

哪个版本的VS？ 2012年没有它们，Nuget包不安装模板，它们只包含二进制文件。从您的日志消息中可以清楚地看到您无法访问Nuget（第二行），但也很清楚您已经引用了SignalR。如果你想添加一个Hub类，只需添加一个简单的类并使其从Microsoft.AspNet.Signalr.Hub派生，你就不需要那个模板了。

使用signalR集线器课程挑战？
