.NET217 titlesString extension method for converting to other value types
0
In many cases serialized data is returned in a form of string although the actual type of data is different. The problem begings when you want to use data in it's original type becaus direct cast is not allowed in C# as it is in VB.net.

.NET217 titlesBinding JSON string to anonyms type
0
JSON is really easy to use and it really boosts performances since it is a lot lighter than XML and SOAP.
