title: Why does the Visual Studio conversion wizard 2010 create a massive SDF database file?
body: <p>I've opened a 2009 C++ sln in 2010 and run the Visual&nbsp;Studio&nbsp;2010 conversion wizard. It seems to have done the conversion fine, but there's a 60&nbsp;MB .sdf file created with the same name as my .sln file (apart from extension)! There was no sdf file before. I'm pretty sure when I've used the wizard on C# projects this file hasn't been created.</p>
  
  <p>It looks like it's created to help the conversion wizard, but I don't see why it's left when the wizard has finished. The tables in the database are:</p>
  
  <pre><code>assoc_spans
  assoc_text
  base_class_parents
  code_item_kinds
  code_items
  config_files
  configs
  file_map
  file_signatures
  files
  parsers
  projects
  properties
  refs
  symbols
  </code></pre>
  
  <p>I assume I can just delete this file?</p>
