title: Visual C# GUI stops responding when process.WaitForExit(); is used
body: <p>I am creating a GUI application using Visual C# 2005 (net framework 2). I use the following code to start a process:</p>
  
  <pre><code>Process process = new Process();
  process.StartInfo = new ProcessStartInfo("app.exe");
  process.StartInfo.WorkingDirectory = "";
  process.StartInfo.Arguments = "some arguments";
  process.Start();
  process.WaitForExit();
  </code></pre>
  
  <p>I want my application to wait until this process is finished, so I used WaitForExit. But the GUI Windows freezes while app.exe is running. I want it to respond (e.g. press a cancel button), but I don't want the code to continue, because there is another process to start after than. Thanks in advance!</p>
