对 signalR 集线器类具有挑战性？

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 但是我在我的新项目 Field 中看不到 Signal hub Classes 。有我的安装消息来自包 =>

                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

                 Attempting to resolve dependency 'Microsoft.Owin.Security (≥ 2.0.1)'.
                 Attempting to resolve dependency 'Microsoft.Owin.Host.SystemWeb (≥ 
                  '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 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出您无法访问 Nuget（第 2 行），但也很明显您已经引用了 SignalR。如果您想添加一个 Hub 类，只需添加一个简单的类并使其派生自 Microsoft.AspNet.Signalr.Hub，您不需要模板。
