title: How to shorten the type names?
body: <p>Hey I'm newbie in C# and I'm wrote this piece of code:</p>
  
  <pre><code>static void Main()
  {
      Dictionary&lt;int, HashSet&lt;string&gt;&gt; dict1 = new Dictionary&lt;int, HashSet&lt;string&gt;&gt;();
      Dictionary&lt;int, HashSet&lt;string&gt;&gt; dict2 = new Dictionary&lt;int, HashSet&lt;string&gt;&gt;();
      // ...
      CompareDicts(dict1, dict2);
  }
  
  private static void CompareDicts(Dictionary&lt;int, HashSet&lt;string&gt;&gt; dict1, Dictionary&lt;int, HashSet&lt;string&gt;&gt; dict2)
  {
      // Blah blah
  }
  </code></pre>
  
  <p>Is there any way to make this code more readable (shorter)?</p>
