.NET 捆绑仅在服务器重新启动时抛出错误

Question

所以我已经捆绑到位，我们有一个由 3 台服务器组成的网络场运行网站。

回收应用程序池时会抛出一些错误，但我不确定如何修复它们（或者如果可能的话）

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

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"));

渲染成这样

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

任何想法

例外情况：

好的，所以想通了，似乎在构建字典时应该在字典上加一把锁。

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:)
