title: C# Interactive window missing method
body: <p>I was trying to test an extension method that I made for <code>IEnumerable&lt;T&gt;</code> inside of the C# Interactive Window that comes with VS2015 and I am having a hard time getting the window to find the method that I defined.</p>
  
  <p>Basically I defined a method as follows:</p>
  
  <p><code>public static IEnumerable&lt;T&gt; AsEndless&lt;T&gt;(this Enumerable&lt;T&gt; currEnum)</code></p>
  
  <p>If I create a new console project and reference my extensions project I can call that extension method just fine, but if I try to do the same thing in the C# interactive window, even after importing the dll with <code>#r 'path-to-dll'</code> I get an error saying that my test <code>List&lt;int&gt; does not contain a definition for 'AsEndless'</code>.</p>
  
  <p>Is it simply not possible to do something like this with the C# Interactive Window?</p>
