Customizing ACS Code Generator DLLs (C# code)
If you want to customize how ACS generates C# code, you must create a customized version of the provided ACS Code Generator DLL.
You create a customized version of the ACS Code Generator DLL by changing the TDK Code Generation Transformation Patterns model from which the ACS Code Generator DLL was generated, and then generating a new ACS Code Generator DLL through TDK.
