Issues with hotfix code doing dll calls

So, observed this issue a few times in the past (the latest one just came across my path), so thought to share my thoughts on this. The problem is when the code is making calls to external libraries, in this case dlls that are part of the AX ecosystem.

So the issue is normal after all to occur. You have installed a new code hotfix (model) and you haven't upgraded your kernel components to the latest build. The code wants to work with the dlls necessary for its version, but instead it finds either old signatures, in which case it will error out, or it doesn't behave as you would expect (old implementation).

So, to outline the idea here, is that when you notice in the code calls to external libraries, make sure first you are using the proper dlls. This is why it is recommended to always try to keep you on the latest kernel binaries.
