title: Microsoft.Office.Interop.Excel Not working correctly
body: <p>I have a Windows Form Application in VS2012 C# and I'm trying to use Microsoft.Office.Interop.Excel; in order to make an Excel spreadsheet. Whenever I try to type some code such as </p>
  
  <pre><code>Application _excelApp;
  </code></pre>
  
  <p>or </p>
  
  <pre><code>var application = new Application();
  </code></pre>
  
  <p>I keep getting the same error which is "Application is an ambiguous reference between 'System.Windows.Form.Application' and 'Microsoft.Office.Inter.Excel.Application'. I was just wondering what the solution is so I could start using the Interop.Excel. Any help would be greatly appreciated. </p>
