51Degrees.mobi strongly believes that one size doesn’t fit all. It’s the reason we created our own mobile device description repository, which enables web designers to create a site that’ll adapt automatically for visitors using mobile phones.
However, it’s important to realise that a choice of just two sizes can also be less than ideal. With consumers now using portable internet-connected devices that range from feature phones to iPads, simply deciding whether or not a handset is ‘mobile’ isn’t always enough.

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.
