title: Data Mining Resources for C#
body: <p>I wonder if we could compile a list of resources for Data Mining in C#?</p>
  
  <p>Specifically I am looking for </p>
  
  <ul>
  <li>Implementations of Data Mining Algorithms</li>
  <li>Open Source Data mining libraries </li>
  <li>Tutorials on Data Mining using C#/.net code</li>
  </ul>
  
  <p>&amp; if anyone knows of a C# implementation of <a href="http://en.wikipedia.org/wiki/C4.5_algorithm" rel="nofollow">http://en.wikipedia.org/wiki/C4.5_algorithm</a> I'd be very interested. </p>
  
  <p>I'll try and summarise the posted results for re-usability</p>
