title: C# and Excel Interop issue, Saving the excel file not smooth
body: <p>I could Open and Write to the excel file, but when I try to save the file by passing a path to it, the save operation prompts with the Save dialog. I was expecting it to quitely Save the file at the specified path</p>
  
  <p>The code is as below:</p>
  
  <pre><code>excelApp.Save(exportToDirectory);
  excelApp.Quit();
  </code></pre>
  
  <p>where, <strong>exportToDirectory</strong> is: "C:\files\strings.xlsx".</p>
  
  <p>PS: I have already checked with the excel version and similar issue.</p>
  
  <p>Thanks</p>
