title: .NET Built-in AVL-Tree?
body: <p>Is there a built in AVL Tree in the .NET libraries?</p>
  
  <p>I searched but didn't find any.</p>
  
  <ul>
  <li>If there is, then where? what namespace?</li>
  <li>If not, is there any good implementation for AVL Trees in C#?</li>
  <li>If also not! then is there an easy way to get it done? I know how it works and have built one in native C++ before, but now I have no time and am afraid of bad performance if I did it myself.</li>
  </ul>
