Interacting with Inventor 2023 using C# .NET 8

[Patrick5200]

Hello everyone,

I've recently started experimenting with writing a standalone program in C# .Net Framework 4.7.2.

Because I could only get the interop DLL to work in this version. (And because I wanted to use WinForms).

Now I like WPF better and have decided to switch to .NET 8, I have heard that Inventor 2025 switches to this Version too. But I only have access to Inventor 2023.

Implementing the identical procedure into the .NET 8 Application to access the Inventor Namespace or Inventor Objects doesn't seem to work as the Namespace isn't recognized after adding a reference to autodesk.inventor.interop.dll.

Is there another way to access Inventor 2023 using WPF or do I just have to wait until I have access to Inventor 2025?

In general you are not able to communicate with Inventor 2023 from .NET 8 application. But you can create WPF application in .NET Framework and communicate with Inventor without any issues.
