When we put a long comment in Summary (including 4 ou 5 lines), and we try to visualyze it, its presented as a continuous line, not respecting the lines breaks and paragraphs. Is there a way to work this around?

Are you referring to XML documentation of XML of C#?

Try 

  /// <summary>
  /// Page Load
  /// </summary>
  /// <param name="sender">System Defined</param>
  /// <param name="e">System Defined</param>
  /// <remarks>
  /// <list type="bullet"><item>A</item><item>B</item></list>
  /// <list type="table"><item>A</item><item>B</item></list>
  /// </remarks>

The buller type will render like

Well, thanks for helping, but then I would have to write a lot of tags just to add a paragraph in Summary. I thought there might be an easier solution fot this.

Thanks again.
