IACADENTITY Error

[hamza_ishtiaqMTF8E]

Hello Team, 

Good Day, I need help in resolving an error i am encountering in my project that i am upgrading from 2020 to 2021. Earlier i was using ObjectARX 2020 files now i am using ObjectARX 2021 files and using Visual studio 2019 as mentioned in Autodesk documentation. I need your help to resolve below error please. 

error BC30652: Reference required to assembly 'AXDBLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' containing the type 'IAcadEntity'. Add one to your project.

It would be appreciated if you may share migration guide from 2020 to 2021.

Thanks,

Usually <ARX>\inc\dbxHeaders.h is included either directly or indirectly in stdafx.h. This header has the line 

#pragma comment (lib ,"axdb.lib")

which should do the trick.

Please make sure that you have adjusted the project settings to the correct <ARX> directory

• C/C++ ->General->Additional Include Directories
• Linker->General->Additional Library Direcories

These directories (and other settings) might be set by property sheets (.props files).

In Visual Studio you can bring up the property manager window via menu [View].[Property Manager]:

Each project configuration can have it's own set of property pages.

If you add a new project configuration for Arx 2021, you should use an appropriate property page for it as well.
