title: Reactive Extensions (Rx) for Silverlight - Where is System.Interactive.dll moved to?
body: <p>I've just installed the newest Release (v1.1.10425) of Rx for Silverlight 4 and 5 (Beta). I've seen that the package is missing 3 DLLs I've used in my projects in the past:</p>
  
  <pre><code>System.CoreEx.dll
  System.Interactive.dll
  System.Observable.dll
  </code></pre>
  
  <p>What I'm actually missing is the following extension method:</p>
  
  <pre><code>System.Linq.EnumerableEx.Run&lt;TSource&gt;(this System.Collections.Generic.IEnumerable&lt;TSource&gt;)
  </code></pre>
  
  <p>Where has it moved to? Was it merged with an other assembly?</p>
