While looking for coding best practices, i discovered this book: http://www.amazon.com/Clean-Code-Handbook-Software-Craftsmanship/dp/0132350882 . It is very easy to read with funny drawings..
The guidelines in  http://csharpguidelines.codeplex.com/ are worth sharing as well..

html vertical line

Unfortunately, there is no explicit element in html in order to draw a vertical line .. However, there are 3 ways to achieve this:

1) With table column: http://stackoverflow.com/questions/3148415/how-to-make-a-vertical-line

<td width="5%"style="border-left: 1px solid black; padding: 5px;">   </td>

2) With 1-pixel image

3) With css (div) 

for 2 and 3 : http://w3cyberlearning.com/html/html_vertical_line.php

Another option is to draw very thick and short horizontal line: http://forum.yola.com/yola/topics/vertical_lines_using_html

error : The underlying connection was closed: The connection was closed unexpectedly.

If the error

{"The underlying connection was closed: The connection was closed unexpectedly."}

blows up for some of the web service methods, while others work correctly, the reason may be the return objects refer to each other in a recursive manner. 

In my condition, i got the error while returning Sentence.

Paragraph() {

     List<Sentence> Sentence;

}

Sentence() {

  List<Paragraph> SomeText;

}

When the type of SomeText is changed from Paragraph  to Sentence, everything works fine!
