X++ vs C# Best Choice AX Programming

(3) ShareShare

Posted on by Community Member

Hi everybody

Here is Maurizio Grisotto from Italy
I'm moving from AX2009/2012 to Dynamics365FO (finally) and I would like to know your opinions about the subject's point

I'm a Senior NET Programmer (>10 years) and since now AX is fully compatible with C# language why should I continue to use the old and limited X++ language?

Which disadvantages/problems may I have with this approach? I mean: I know that AX Programmer could not necessary to be a NET programmer but in a world (company and region) where it is most common to find people with NET skills than X++, IMHO, could be a better solution to develop new code

For example

- I think could be an excellent choice using LINQ framework instead of X++ SQL syntax

- Power of NET Framework classes compared to X++ is out of the question

What do you think about it?

Thanks to everyone who will share their views

    If you have experience, then the transition is very profitable. Please note that existing X++ code may require conversion. I recently wondered how to write a software requirement using C++, and found a software requirement document for this. Of course, not everything is clear the firts time. I think i will heve to suffer before I achieve success. In general, I wish you good luck.

    Same here, I too think we should use c# instead of x++.

    Well, this has changed in D365FO. No interop is needed between CRL (".NET") and X++ runtime, because there is no X++ runtime anymore. X++ is compiled to CIL and executed by CLR as any other .NET application.

    Hello Grisotto,

    X++ comes with AX natively. I believe its performance should be better than C# as C# needs interop between X++ and .Net.

    You're wrong in thinking that you can forget X++ and use C# instead of it. Therefore the answer to "why should I continue to use the old and limited X++ language" is "because you have no choice".

    It's true that integration with C# libraries is easier with every version, but it doesn't mean that you can use it instead of X++. Sometimes it useful to write a library in C# and utilize things like LINQ (which was true in AX 2012 as well), but you can't, say, implement an AX form in C#.

    Also note extensibility features such as CoC are specific to X++.
