title: AssemblyFileVersion attribute is being ignored
body: <p>I am having a problem getting the AssemblyVersion to be different from the AssemblyFileVersion attributes in a class library I am working on.</p>
  
  <p>So, I've tried creating an empty (apart from Class1.cs) class library to see if it's a setting somewhere, but I get the same behaviour.</p>
  
  <p>It seems the AssemblyVersion attribute is just being ignored.</p>
  
  <p>Here is the relevant bit from my AssemblyInfo.cs file ...</p>
  
  <pre><code>[assembly: AssemblyVersion("0.1")]
  [assembly: AssemblyFileVersion("1.1.0.9")]
  </code></pre>
  
  <p>and here is how things look in windows explorer ...</p>

  <p>Is there a setting somewhere that controls this?</p>
  
  <p><strong>EDIT:</strong>
  I've found one file where there is a difference, so it's not windows explorer showing the same value for two different fields, it's something to do with the way the DLL is generated from the compiler/linker ...</p>
