51Degrees.mobi has a proven record of fast, reliable detection on ASP.NET website but it has always been restricted to environments within IIS. The 1.2 release has now changed this and detection can now be used offline outside of IIS from any .NET code. To show how, I have made two example projects showing local based detection; a lightweight command line implementation, and a slightly more advanced GUI driven based version.

Forward thinking web sites will have at least 2 different versions of their content. 1 for mobile browsers, and the other for the big screen desktop and laptop devices. 51Degrees.mobi does an excellent job of detecting the device type and redirecting the device to the correct content. To provide users with choice and enable them to switch between the different versions.
