使用 Windows 10 Technical Preview 工具,尝试将最新版本的 SignalR 添加到通用应用平台项目会导致错误:
"Sequence contains more than one element".
添加以前的版本(2.1.2)有一个警告:构建应用程序后,Visual Studio 将提示错误:
Unable to activate Windows Store app The {application} process started, but the activation request failed with error 'The app didn't start'.
这是因为包将app.config添加到项目中,并引用其依赖项。删除app.config,允许项目构建和运行。
