What is dictionary compaction support?
<p>"Here is the implementation of the dictionary without any compaction support."</p>

<p>I know jaredpar is a member on here and posts on the C# section. What exactly is "dictionary compaction support"? I am assuming it is some way to optimise or make it smaller? But how (if this is what it is)?</p>

<p>Thanks</p>
