Equivalent of Copy to Output Directory for DNX applications
<p>I have a Dnx451 MVC web application and I want to copy a <code>.txt</code> file to the output directory to make it easier to copy my application files.</p>

<p>I have added the file to my project at the same level as <code>project.json</code> and added the following to my <code>project.json</code> file.</p>

<pre><code>"content": [
   "file.txt"
]
</code></pre>

<p>But when I build the application the file isn't copied to the output location. In previous versions, I would have just set the Copy to Output Directory option in the file properties, but that doesn't exist in a DNX project.</p>

<p>What is the equivalent process of Copy to Output Directory to get a content file copied to the output directory?</p>
