title: WebGrease warning when building a deployment package
body: <p>Getting the following warning from aspnet_compiler.exe when building a deployment package:</p>
  
  <pre><code>ASPNETCOMPILER(0,0): Warning : The following assembly has dependencies on a version of the .NET Framework that is higher than the target and might not load correctly during runtime causing a failure: WebGrease, Version=1.6.5135.21930, Culture=neutral, PublicKeyToken=31bf3856ad364e35. The dependencies are: System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089. You should either ensure that the dependent assembly is correct for the target framework, or ensure that the target framework you are addressing is that of the dependent assembly.

  <p>Same thing happened before I updated WebGrease from version 1.3.0.0
  Tried both of the following assembly bindings without success:</p>
  
  <pre><code>&lt;dependentAssembly&gt;
      &lt;assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" /&gt;
      &lt;bindingRedirect oldVersion="0.0.0.0-1.6.5135.21930" newVersion="1.6.5135.21930" /&gt;
    &lt;/dependentAssembly&gt;
  
  &lt;dependentAssembly&gt;
      &lt;assemblyIdentity name="System.Windows.Forms" publicKeyToken="b77a5c561934e089" /&gt;
      &lt;bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" /&gt;
  &lt;/dependentAssembly&gt;
  </code></pre>
  
  <p>I spent 2 days on this already frying different configurations and would greatly appreciate any hint or help.</p>
