Throughout last few months i had a chance to work with AS400, Equation APIs. The purpose of these equations calls are that we have to develop WCF services on top of these API calls. These calls will be consumed by the BizTalk. Initially it was too hard as i couldn't find any resources online. When i searched in gOOgle about the errors which come across at the time of developments, it does not return anything! It was some hard times and thank for my team lead for helping out on those situations. Hope to write something about AS400, C# in coming days…
Here is the lovely interface of Equation.
