title: Click once temporary folder
body: <p>I am working on a Winforms app that is deployed using <em>ClickOnce</em>. In the clickonce deployment, there are two exe's which I will call viewer.exe and editor.exe. </p>
  
  <p>There is an option in the viewer which dumps a bunch of files to a temporary directory and then instructs editor.exe to launch and open all files in this directory. </p>
  
  <p>My problem is that I can't figure out a place within the ClickOnce folder structure that will let me create a temporary folder to dump these files to. Whenever I try to create a subdirectory in <code>ApplicationDeployment.CurrentDeployment.DataDirectory</code> I get an error message that:</p>
  
  <blockquote>
    <p>[I don't] have permissions to access that directory.</p>
  </blockquote>
  
  <p>Is there any place within the ClickOnce framework that will let me create a folder to dump files to?</p>
