字体文件未与 ASP.NET Bundle 一起加载

在我的ASP.NET MVC应用程序，我正在使用Bundle 包压缩css和js文件.问题是，启用优化模式后字体没有加载.

BundleTable.EnableOptimizations = true;

下面是C#代码

public static void RegisterBundles(BundleCollection bundles) {
    RegisterStyles(bundles);
    BundleTable.EnableOptimizations = true;
}

private static void RegisterStyles(BundleCollection bundles) {
bundles.Add(new StyleBundle("~/BundleStyles/css").Include(
    "~/Content/Styles/bootstrap/bootstrap.css",
    "~/Content/Styles/reset.css",
    "~/Content/Styles/gridpack/gridpack.css",

    "~/Content/Styles/fontFaces.css",
    "~/Content/Styles/icons.css",

    "~/Content/Styles/inputs.css",
    "~/Content/Styles/common.css",
    "~/Content/Styles/header.css",
    "~/Content/Styles/footer.css",
    "~/Content/Styles/cslider/slider-animations.css",
    "~/Content/Styles/cslider/slider-base.css"));
}

这里是字体的css.

   @font-face {
      font-family: ProximaNova;
      src: url('../Fonts/ProximaNova/ProximaNova-Bold.otf') format('opentype');
      font-weight: bold;
      font-style: normal;
    }

下面是CSS在页面中的引用方式.

<link href="/BundleStyles/css?v=pANk2exqBfQj5bGLJtVBW3Nf2cXFdq5J3hj5dsVW3u01" rel="stylesheet"/>

然而，当我使用Chrome调试器工具进行判断时，字体文件没有加载到页面，并且我的页面因字体错误而看起来很糟糕.

我做错了什么？
