title: How to copy a VSTO Document level worksheet without registery installation?
body: <p>My understanding is that when I create a workbook VSTO solution, I need to register (implicitly or explicitly) the solution in the registry. When developing the VS takes care of this.</p>
  
  <p>If I wanted to have more than physical xlsx files with different names and reuse the VSTO code what to do?</p>
  
  <p>A simple copy/paste of the workbook file won't work of course. I don't want to register each new workbook in windows registry since this could be a serious hassle.</p>
  
  <p>Typical case would be: Say a user collects monthly data in workbook xlsx file. You need to run the VSTO code in each workbook xlsx file separately. As a result you end up having 12 sheets per year. Using VBA, you could easily copy the files and change the names - How to do the same when VSTO is used?</p>
  
  <p>I thought of using a template but I wanted to ask before I waste time on it.</p>
  
  <p>I am using VS2010, C#, Excel 2007.</p>
