带有控制台/Windows服务示例VS2010的signalR自主机

【中文标题】带有控制台/Windows服务示例VS2010的signalR自主机

【英文标题】：signalR self-host with console/windows service examples VS2010

【问题描述】：

所以我找到了关于 SignalR v2 的各种点点滴滴，它似乎只是 VS2012/2013 (.net 4.5)。

任何人都可以提供有关如何使用 VS2010 (.net 4) 在 winforms/console/windows 服务中自我托管的服务器/客户端示例。设法让 SignalR v1 + VS2010 + ASP.NET 聊天应用程序最终与较低版本的客户端/服务器一起工作。

我看到各种带有 WebApp.Start(url) 或 WebApplication.Start(url) 的文章 (Regarding hosting SignalR in console apps) 但我要么没有参考资料，要么没有东西让它与 VS2010 一起工作。

我不确定示例是否像； http://mscodingblog.blogspot.co.uk/2012/12/testing-signalr-in-wpf-console-and.html可以在VS2010中完成。

我已经设法将SignalR Console app example 转换为VB，最终确定服务器的版本需要是0.5.2 和Microsoft.AspNet.SignalR.Client 1.0.0-alpha2

我看到 SignalR v1 升级到 1.2.2，我想我需要匹配类似性质的服务器主机/OWIN，但找不到适用于 VS2010 的示例。

看了SignalR support in .NET 4

提前致谢。

【参考方案1】：

最终装了VS2013 CE看例子。

找到了一些使用 VS2013 与 .net 4.0 配合使用的示例。 例如http://mscodingblog.blogspot.co.uk/2012/12/testing-signalr-in-wpf-console-and.html

将示例复制到 VS2010 .NET 4.0 中的项目中。

在版本等的代码中添加了 cmets，哪些有效或无效。
