Everyone loves well commented code [when they are reading the code] but when it comes to add comments in their own code, well people are not that generous. And it is not that they don’t want to add comments but XML adding XML comments to event handler can be really really tedious and kills productivity. So if you love to comment your code but have to skip it ’cause it is a lot of extra work then look no further. Here is a Visual Studio add-on that I have used for quite a while. It is called Ghost Doc [http://submain.com/products/ghostdoc.aspx]. It is pretty simple to use and has a rich set of configuration option. If you are looking for more options than there is a licensed version with more features [document entire type/file] is also available.
Check out the following video[Source: submain.com] to see how it works.
