In AX 2012 R3 cu12, we developed our own internal TMS engine to call 3rd party web services. In AX 2012 version, this required us to customize from the AOT >Visual Studio Projects > C Sharp Projects > Microsoft.Dynamics.AX.TMS
Within VS, we modified (add 1 line of code) Utility > XDocExtensions.cs
... Now in D365 I have found the C# class under AOT > References > Microsoft.Dynamics.AX.TMS.Base which is where this has been moved. How do we go about making changes to integrate our code? LCS just left this out when we ran the upgrade analysis.
