Create Paper Space Viewports (.NET)

The Dll Import should be from "accore.dll" NOT from "acad.exe"
and the entry point is incorrect.

The following options work for me in ac2023


--- Code - C#: ---     //---------------------------------------------------------------------------      [DllImport("accore.dll", CallingConvention = CallingConvention.Cdecl,         EntryPoint = "?acedSetCurrentVPort@@YA?AW4ErrorStatus@Acad@@PEBVAcDbViewport@@@Z")]              extern static private int acedSetCurrentVPort(IntPtr AcDbVport);      //---------------------------------------------------------------------------      [DllImport("accore.dll", CallingConvention = CallingConvention.Cdecl,          EntryPoint = "?acedSetCurrentVPort@@YA?AW4ErrorStatus@Acad@@H@Z")]      private static extern int acedSetCurrentVPort(int acDbVportNumber);      //---------------------------------------------------------------------------  
I imagine there are a few others that have been incorrect for about 9 years or so.

The current Dumpbin output is here:

live long and prosper.

Alternate solution from Gilles
and revised code for multiple Viewport creation ( to avoid Acad crash )
