I am not able to access the methods(like GetACADHandleFromItem()) of FabricationAPI.dll & FabricationCore.dll of 2019 version in .Net framework 4.7.1.

Is there any compatibility problem between Fabrication CADMep dlls of 2019 version & .Net framework 4.7.1?

How to access fabrication 2019 dlls in my project?

Can anyone help me with the above issue?
