title: MSBuild exec task without blocking
body: <p>Would anyone happen to know a trick that will keep this MSBuild task from blocking? I really just want the explorer to open and the build script to keep on going. Currently it blocks at the Exec task until the explorer window is closed.</p>
  
  <pre><code>&lt;Target Name="OpenExplorer"&gt;
      &lt;Exec Command='explorer.exe "$(DestinationDir)"' IgnoreExitCode="true" /&gt;
  &lt;/Target&gt;
  </code></pre>
  
  <p>Thanks!</p>
  
  <p><strong>Edit:</strong> I was hoping to avoid creating a custom task for this. Perhaps some command line magic exists that could be placed inline for the <code>Command</code>?</p>
