I require a API use or similar use to get the full urls from a shortened one. The solution must be able to solve tinyurl and [url removed, login to view] and other widely used ones in twitter.
The application can be in windows forms or windows (web form) but must be able to interface into .NET and C#.
The application will have a class or classes which take the shortened url with an identifier for the type (eg tinyurl, bit, ) and it will return the full url.
I know [url removed, login to view] is also used in twitter and some others, I only need commonly used ones.
The application will process several in one go, and efficiency is an important consideration.
