title: With ResourceManager, why does it work when I call GetStream(...) before GetResourceSet(...)
body: <p>I have a strange issue with the C# ResourceManager. The following kind of fails:</p>
  
  <pre><code>var rm = new ResourceManager(typeof(myStrings));
  var resources = rm.GetResourceSet(culture, false, false);
  </code></pre>
  
  <p>Now 'resources' is null. But the following works:</p>
  
  <pre><code>rm.GetStream(""); 
  var resources = rm.GetResourceSet(culture, false, false);
  </code></pre>
  
  <p>Why does it only work when I call .GetStream("") first?</p>
