[英]Why SignalR is not loaded properly when my ASP.NET MVC application is published on IIS using bundle optimization?
似乎在使用带有IIS的开发服务器上的SignalR运行我的应用程序时，我在JS控制台中收到以下错误（尽管在Debug中本地运行该应用程序完全可以）：
Uncaught Error: SignalR: SignalR is not loaded. Please ensure jquery.signalR-x.js is referenced before ~/signalr/js. at hubs:17 at hubs:106
第17行与以下内容有关：
if (typeof ($.signalR) !== "function") {
throw new Error("SignalR: SignalR is not loaded. Please ensure jquery.signalR-x.js is referenced before ~/signalr/js.");
}
第106行只是IIFE的结尾。
以下是BundleConfig类：
public class BundleConfig
{
public static void RegisterBundles(BundleCollection bundles)
{
var scriptBundle = new ScriptBundle("~/Scripts/bundle");
// jQuery
scriptBundle.Include("~/Scripts/jquery-3.1.1.min.js");
// Bootstrap
scriptBundle.Include("~/Scripts/bootstrap.min.js");
// Knockout
scriptBundle.Include("~/Scripts/knockout-{version}.js");
// SignalR
scriptBundle.Include("~/Scripts/jquery.signalR-{version}.js");
// Custom site scripts
scriptBundle.Include("~/Scripts/scripts.js");
scriptBundle.Include("~/Scripts/scripts-bootstrap.js");
scriptBundle.Include("~/Scripts/scripts-devextreme.js");
var styleBundle = new StyleBundle("~/Content/bundle");
// Bootstrap
styleBundle.Include("~/Content/bootstrap-telus-theme.min.css");
// Font Awesome
styleBundle.Include("~/Content/font-awesome.min.css");
// Custom site styles
styleBundle.Include("~/Content/Site.css");
styleBundle.Include("~/Content/Site-bootstrap-plus.css");
styleBundle.Include("~/Content/Site-devextreme-plus.css");
bundles.Add(scriptBundle);
bundles.Add(styleBundle);
#if !DEBUG
BundleTable.EnableOptimizations = true;
#endif
}
}
开发服务器上的文档类型如下：

开发服务器上发布的内容没有使用DEBUG常量运行，如果没有它，我如何使它工作？ Imho BundleTable.EnableOptimizations = true; 线不应该弄乱我的signalR捆绑，但这仍然是我可以看到的唯一的区别。 但是，当在本地使用开发服务器配置运行时，即使启用了优化捆绑包，它也可以工作...
发生此问题是因为捆绑包优化正在跳过最小文件。 而且您捆绑的JS没有jQuery，这是SignalR必需的。
有关更多详细信息，请检查以下答案： 捆绑软件不包括.min文件
