クラス

AcadApplication
       Minor version number of the class has been incremented from 23.0 to 23.1

       Use the ProgID AutoCAD.Application.23.1 to create an instance of AutoCAD 2020 or 
       ProgID AutoCAD.Application.23.0 to create an instance of AutoCAD 2019, when installed.

       ProgID AutoCAD.Application.23 can still be used to create an instance of AutoCAD 2020, but 
       there will be inconsistencies in execution when installed side-by-side with AutoCAD 2019.
