Asp.Net - what is <%$?
<p>I should know this by now, but I don't, and for some reason, I am not finding the answer on Google, so I thought I'd try here.</p>

<p>I know that <code>&lt;%=  %&gt;</code> is the equivalent of <code>Response.Write()</code></p>

<p>And I've seen <code>&lt;%#  %&gt;</code> for databinding.</p>

<p>However, today I noticed something new, and even though I can see what it's doing, I am looking for the official documentation on this.  In one of my web pages, I see </p>

<pre><code>ConnectionString="&lt;%$ ConnectionStrings:SomeConnectionString %&gt;"
</code></pre>

<p>So what does <code>&lt;%$  %&gt;</code> do?</p>
