If you are interested in Episerver Commerce development, I have something for you. I’ve written two books on the subject, or rather, two only books on the subject.
The first book is Pro Episerver Commerce: Building powerful eCommerce solutions. This aims to provide both overview, and, in depth insight into Episerver Commerce, the concept/idea behind the framework, and how to make it work for you.
The second one is Episerver Commerce: A problem – solution approach. This aims to be a recipe book. You got a problem, you find a solution. Simple as that.
Both can be purchased on leanpub.com
You can buy both of them as bundle, at a discount, at https://leanpub.com/b/epicommercedevelopment . I usually offer discounts on special occasions, so make sure to check it out.
