New, But Not So Obvious, Features in .NET 4.0

.NET 4.0 came out lately with a lot of new, cool, and somewhat game-changing features. These features include language features like the famous dynamic keyword in C# and this whole dynamic dispatching thing that made possible by the DLR (Dynamic Language Runtime).There are also some additions on the library level, the parallel extensions is an obvious example of that.

In this post I will mention some of the new additions that are not so well propagated.

First The additions to the string class:
The BCL guys are still working on the core. Apparently they are trying to lessen the number of extension methods that you need to write as a complement to some of the very core, and widely used in any application, classes -Pretty much everyone has a StringExtensions, and DateTimeExtensions dlls.

string.IsNullOrWhiteSpace()

The old string.IsNullOrEmpty() was used to check if the string variable is null or if it's equal to the empty string ("", or string.empty)In many cases a string that contains only white spaces is considered to be an empty string. People used to do the following check over and over again:

if ( string.IsNullOrEmpty(s) && s.Trim() != string.Empty )  
{  

// do my job;  

}
