Opening C# code files from Modeler (C# code)
After ACS generates C# code files, you can open those code files from items in Modeler.
To open a C# code file from Modeler
1. From Modeler, locate the Model, Package, Class, Data Type, Interface or Signal from which the code file was generated.
2. Right-click the item, and then click Open C# File.
The file is opened in the application associated with the code file's extension.
