title: Configure Visual Studio 2013 to allow ASPNETCOMPILER to precompile using the x64 compiler
body: <p>How can I use the "Precompile during publishing" flag on a VS2013 x64 project? No matter what I do, it fails to publish because it insists on using the x86 ASPNETCOMPILER.</p>
  
  <p>I think I used to have this working in VS2012, but after upgrading to VS2013 it is no longer working.</p>
  
  <p>I recall the fix involving changing a text file related to <code>MSBuild</code> but I honestly don't know very much about it so it's a little hazy.</p>
  
  <p>Any help is greatly appreciated. Thanks!</p>
