Implementation

I saw the following namespace implementation in an article and i really can't get the point why they did so?

using sysConfig =System.Configuration ;

string connectionString = sysConfig.ConfigurationManager.
                         ConnectionStrings["connectionString"].ConnectionString;

I know It can be easily implemented like this,

string connectionString = System.Configuration.ConfigurationManager.
                         ConnectionStrings["connectionString"].ConnectionString;

Any suggestion when to use the first type...

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy.
