Visual Studio 2012 not picking up latest compiled TypeScript for ASP.NET MVC4 project

How do I force Visual Studio 2012 to always use the most recent version of the generated JavaScript file created by TypeScript?

I am using the following definition in my project file:

<Target Name="BeforeBuild">
    <Exec Command="&quot;$(PROGRAMFILES)\Microsoft SDKs\TypeScript\0.8.0.0\tsc&quot; -out scripts\app.js scripts\app.ts  -target ES5 @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" IgnoreExitCode="true" />
  </Target>

When I clean and rebuild the project, app.js is updated accordingly.

However, for some strange reason, when I try to debug the solution using Internet Explorer, Visual Studio is using an outdated version of app.js, which invalidates my breakpoints.

What is going on here?

The most likely problem here isn't really TypeScript or JavaScript - Internet Explorer is just caching the JavaScript file and using the out-dated version.

If you are referencing an individual script, you can cache-bust it by changing an arbitrary part of the URI:

<script src="myscript.js?1"></script>

If you increment the 1 each time you want to replace the cached version, it will cause the new script to be loaded. You could automate this by dumping a timestamp in place of the 1.

If you are using bundling, which I recommend in MVC4, the bundler will append a hash of the scripts, which does the same thing.
