title: What does () => mean in C#?
body: <p>I've been reading through the source code for <a href="http://code.google.com/p/moq/" rel="nofollow noreferrer">Moq</a> and I came across the following unit test:</p>
  
  <pre><code>Assert.Throws&lt;ArgumentOutOfRangeException&gt;(() =&gt; Times.AtLeast(0));
  </code></pre>
  
  <p>And for the life of me, I can't remember what () => actually does. I'm think it has something to do with anonymous methods or lambdas. And I'm sure I know what it does, I just can't remember at the moment....</p>
  
  <p>And to make matters worse....<a href="http://www.google.com.au/search?hl=en&amp;q=%28%29+%3D%3E&amp;btnG=Google+Search&amp;meta=&amp;aq=f&amp;oq=" rel="nofollow noreferrer">google isn't being much help</a> and <a href="https://stackoverflow.com/search?q=%28%29+%3D%3E">neither is stackoverflow</a></p>
  
  <p>Can someone give me a quick answer to a pretty noobish question?</p>
