title: Microsoft.Office.Interop.Excel is too slow
body: <p>I'm using the Excel Interop and I have an object list. It takes too long when I set the properties of the objects in the list in Excel cells in a loop:</p>
  
  <pre><code>        workSheet = (Excel.Worksheet)wbook.ActiveSheet;
          var row = 1;
          foreach (var shiftStop in shiftStops)
          {
              row++;
              workSheet.Cells[row, "A"] = shiftStop.MachineName;
              workSheet.Cells[row, "B"] = shiftStop.MachineType;
              workSheet.Cells[row, "C"] = shiftStop.UnitName;
  
          }
  </code></pre>
  
  <p>The <code>shiftStops</code> list has about 4000 objects. It takes 4-5 minutes to complete the return. Is there a way to make this process faster?</p>
