GetObject autocad application issue in autocad 2025

Hi Everybody, Good Day.

I am developing software using Visual Studio 2022 and autocad 2025. The software starts with .Net 8 COM and after autocad opens, it calls .Net 8 DLLs using sendcommand. The issue is, everytime i start the software, i have to create a new Application instead of using existing application.

Try Acadapp = GetObject(, "Autocad.Application") Catch ex As Exception End Try Try Acadapp = GetObject(, "AutoCAD.Application.25") Catch ex As Exception End Try Try Acadapp = GetObject(, "AutoCAD.Application.25.1") Catch ex1 As Exception End Try Try Acadapp = GetObject(, "AutoCAD.Application.25.0") Catch ex1 As Exception End Try Try Acadapp = GetObject(, "AutoCAD.Application.25.2") Catch ex1 As Exception End Try Acadapp = CreateObject("AutoCAD.Application")

In the simple code, above, getobject never fetches autocad application. I tried to start without /nologo. Even then it does not work. Please help me.

Have a look at this link:

"The GetActiveObject method is deprecated in .NET 8, specifically starting from .NET Core 3.0. The Marshal.GetActiveObject() API is a simple wrapper over the Running Object Table (ROT) and relies on folllwing Win32 APIs that can easily be called via P/Invoke."
