I am happy to announce that IE6 is not supported by UI for ASP.NET AJAX as of Q2 2014. The outdated and insecure browser reached the end of its life with the Microsoft discontinuation of Windows XP in April 2014 , since Windows XP is the last OS that could have it.
Let's get down to some of the reasoning behind our decision to drop the support of IE6 and see what's next and how it impacts your development.
If the short answer "because we finally can" does not suffice, here is a list of reasons and benefits for you:
If you still need to run your site under IE6, you may experience the following issues:
At this point we are not going to modify the scripts we use, so things should be OK. Note that this may change in the future, as that's the point of dropping support for an obsolete technology—to make way for improvements available in more modern environments.
So, with one dinosaur fossilized, we still have to tackle its close cousins—IE7 and IE8, to begin with. Thus, it is safe to say that IE7 is the new IE6, because it seems Microsoft will support it together with Windows Vista until 2017. That's only three years from now, so you may want to start preparing for that by phasing out its support from your applications. This includes the compatibility mode in IE8, 9 and 10 too, so removing it suddenly may cause quite a bit of commotion.
If you can make your client/organization use a modern browser such as IE11, Firefox or Chrome instead of IE7, for example, that would be a victory for everyone—you will have less to tackle and your end users will have a better experience.
New York Times have dropped support even for IE8. Many other sites also warn you about using obsolete or unpopular browsers because they aim at providing the best possible experience for their users and sometimes, some features simply cannot be achieved in old browsers.
My personal opinion is that we can advise our employers, colleagues, customers, friends and family to use modern browsers! We, the developers, are the ones to benefit from their adoption when we are no longer held back by obsolete technology.
If you are stuck on IE6 and you are experiencing any problems with it after Q2 2014, we could provide you with limited assistance through the support ticketing system .
