Hi. Just a note that Packt Publishing, the publisher of my Ext.NET Web Application Development book, is running a massive sale campaign.
All books, including mine, at $5 (in UK it is £4) until 8th Jan 2016. Get it here.
Although my book was written a while back and aimed at Ext.NET 2.x, it is still quite applicable for the current Ext.NET 3.x release – especially at that bargain price 🙂
Hope that helps!
