SignalR v2.2.0 發布，一個ASP.NET實時 Web庫

ASP.NET SignalR 是為 ASP.NET 開發人員提供的一個庫，可以簡化開發人員將實時 Web 功能添加到應用程序的過程。實時 Web 功能是指這樣一種功能：當所連接的客戶端變得可用時服務器代碼可以立即向其推送內容，而不是讓服務器等待客戶端請求新的數據。SignalR 可以用于將任何種類的“實時”Web 功能添加到您的 ASP.NET 應用程序。雖然我們經常把聊天應用作為最常用的一個例子，但實際上你可以利用它做很多事情。如果用戶是通過刷新 web 頁面，來查看新的數據，或者是通過頁面實現長輪詢來檢索新的數據，那么就該考慮使用 SignalR 了。
