title: what is a projection in LINQ, as in .Select()
body: <p>I typically do mobile app development, which doesn't always have .Select. However, I've seen this used a bit, but I don't really know what it does or how it's doing whatever it does. It is anything like</p>
  
  <pre><code>    from a in list select a // a.Property // new Thing { a.Property}
  </code></pre>
  
  <p>I'm asking because when I've seen code using .Select(), I was a bit confused by what it was doing.</p>
