Using AX 7 container in C#

(0) ShareShare

Posted on by Community Member

In AX 2012, we had the functionality to use Axapta containers in c# by means of the business connector. Now that the business connector has been depreciated in AX Online, is there any other way we can make use of containers in .net or c# code?

    What are you trying to achieve?

    By the way, please separate tags by comma; you've attached a single long tag "container axapta online ax7 business connector. I'll fix it for you this time.

    Basically, we have ax classes that take containers as parameters and return containers as a result. These classes are used to integrate ax 2012 with a web portal.

    Just wondering if there is another way (other than using business connector) to use containers in C# from AX Online. This would reduce a lot of re-work on the existing classes (around 200).

    thanks

    All right, so now the question stays: Why do you have methods accepting and returning containers to and from a web portal? What are you trying to achieve by that? Do you exchange binary data, such as PDF files, or just regular values. If it's the latter case, what advantage do you get from using containers instead of classes? I would argue it's a wrong design, leading to error-prone code (because the lack of compile-time type control and such things).

    Thanks for the reply Martin, I do agree with you that it is not the best design. But these classes have been developed since AX 2009, upgraded to 2012, and now will be upgraded to AX7. Additionally, these classes where developed by another software vendor, and we are looking into reducing the rework for the upgrade process.

    To give you an example of how the classes work, lets take a sample class - getCustomerInfo.

    Like all the other classes, this class takes a few parameters, which are built from the portal and converted into an Axapta container. The AX class then executes certain functionality inside AX, and will return a result (either the customer, or a list of error), all of which within a container. They are then read inside the portal and displayed to the user.

    I hope that I made the situation a little clearer.

    You deal with technical debt - when somebody did something wrong in past and it's causing more and more problems on the way (interest) unless somebody finally pays the debt (and rework the bad solution to something sensible).

    When moving from BC, you have to change your implementation anyway and trying to keep this ugly anti-object-oriented design just makes no sense. You would spend a lot of time and energy trying to re-implement a thing that was wrong even in AX 2009 and which would increase your maintenance costs. There is simply no good reason to do that.

    Creating a contract class and using it instead of the container is work for a few minutes.
