【问题描述】：
我在 VS 2013 中启动了一个新的 MVC Razor 测试 Web 项目。我将所有 NuGet 包更新到今天的最新版本，并开始包含来自另一个项目的我的 TypeScript 插件进行测试。其中一个插件导致了这个运行时错误：
堆栈跟踪错误：
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

我删除了所有代码和文件，直到我把它缩小到一个失败的例子：
BundleConfig.cs
bundles.Add(new ScriptBundle("~/bundles/ListView").Include(
"~/Scripts/Vero/reorder.ts"));
重新排序.ts
module Plugins
{
export interface IReorderOptions
{
onChange: { (): void; }; // Function to call after update
}
}
母版页_LayoutHome.cshtml：
<!DOCTYPE html>
<html>
[SNIP]
<body>
[SNIP]
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/bootstrap")
@Scripts.Render("~/bundles/ListView")
@RenderSection("scripts", required: false)
</body>
</html>
我的主页/索引引用母版页：
@{
ViewBag.Title = "Home Page";
Layout = "~/views/shared/_layoutHome.cshtml";
}
基本上，构建 JS 输出/捆绑包的代码似乎破坏了我的接口与函数的声明，但我找不到它的模式。
完整的插件在以前的 Web 应用程序中运行良好，所以我怀疑其中一个 NuGet/VS 工具已经改变。 reorder.js 输出文件明显是空的，所以看起来可能是 TypeScript 解析的。
我希望堆栈跟踪（上）和日志（下）提供线索。我希望这实际上是我遗漏了一些明显的东西，或者声明做错了。
输出日志（由于 SO 大小限制，最后一部分）：
