Any version will do because since you communicate with CATIA via COM which is available since .NET 2.0

Strange. I've been working for years in a laptop with visual studio 2019 and .net framework 4.7.2 and everything works!

Now I've upgraded to a new laptop installed visual studio 2022 net framework 6.0. The old created projects, i'm able to run, edit and work. The new created projets, I'm not able to create the com connections. Don't know why, I'm not able to connect with CATIA.

I've made a work around, but it's not a way of working. I had gone to my old laptop, started a new visual studio project, copy the project to the new laptop and work. But not the way that should be. I need to understand what's happening.

Your question is not specific to CATIA, but to .NET and can be answered on any dedicated forum (stackoverflow).

In general, you want to migrate old interop code to new .NET versionq

So not related with .net Framework?

New .NET versions (called ".NET core") don't have same interop APIs compared to old versions (called ".NET framework"). So short answer: create .NET framework projects and target net4.7.2 or net4.8

See this question about accessing active COM server in .NET core -

Again, it has nothing to do with CATIA and it's releases, you'll get same problems with Excel, Word etc.

Hello,

It looks that CATIA is only possible to connect wit .net Framwork 4.8. Anyone of the users that make apps for CATIA by vb.net confirm it?

Up to or ... only ?
I am able to connect with 4.6.1

 

[Little Cthulhu]

Doable with any version of .NET, it's just newer ones require WinAPI calls to be made manually -

[TiagoFigueiredo]

So, resuming, if I want to make the connection with Framework 6, how to do it?
