c# - .NET 捆绑仅在服务器重新启动时引发错误

问题描述

所以我已经进行了捆绑，我们有一个由 3 台服务器组成的网络农场运行该网站。

当应用程序池被回收时，会抛出一些错误，但我不确定如何修复它们（或者是否有可能）

.NET 框架目标版本是 4.5.1 在包管理器中说我有 Microsoft.AspNet.Web.Optimization 版本 1.1.3 最新

Bundle 是这样设置的

var bundles = BundleTable.Bundles;

bundles.Add(new StyleBundle("~/Themes/Mine/Content/bundling/css/header-styles").Include(//line 168
    "~/Themes/Mine/Content/css/styles.css",
    "~/Themes/Mine/Content/css/bootstrap.css",
    "~/Themes/Mine/Content/css/responsive.css"));

它是这样渲染的

@Styles.Render("~/Themes/Mine/Content/bundling/css/header-styles")

有任何想法吗

这是一个例外：

解决方案

好的，所以想通了，似乎在构建字典时应该在字典上放置一个锁。

var bundles = BundleTable.Bundles;

lock (bundles)
    {
        bundles.Add(new StyleBundle("~/Themes/Mine/Content/bundling/css/header-styles").Include(
            "~/Themes/Mine/Content/css/styles.css",
            "~/Themes/Mine/Content/css/bootstrap.css",
            "~/Themes/Mine/Content/css/responsive.css"));
    }

希望这对其他人有帮助:)
