title: Visual Studio compile - Change DLL File Description
body: <p>I have a .NET 4.0 ASP.NET WebApp Project with the following AssemblyInfo.cs:</p>
  
  <pre><code>#if(Development)
  [assembly: AssemblyDescription("Development")]
  #elif(Test)
  [assembly: AssemblyDescription("Test")]
  #elif(Production)
  [assembly: AssemblyDescription("Production")]
  #endif
  </code></pre>
  
  <p>After I compiled the project in Visual Studio 2012, I checked the "File Description" property in the Details tab of the Windows Properties dialog for a file and it is empty. How can I set the File Description?</p>
