run addin building with .NET 8 in inventor 2024

[jose_loaiza5W6L6]

Hello everyone, I hope your are very well

I developed an addin for inventor 2025 with.NET 8,  now the requirement is to run with inventor 2024 as well. My question is, must I create a new project with.NET Framework 8 to run into inventor 2024, or is there any approach where I can use my actual project with .net 8 to run into 2024?

The Idea is not to have two projects for many reasons: maintenance, productivity, security, and reliability

I appreciate any help.

Thank you so much

@JelteDeJong has a great topic on this you can compile it twice differently. Have a look on his site please...

I copy solution file (.sln) and change target.

I do this to target different IV version.

Should work with targeting different .Net.

Set it to build to different folder.

You dont need to copy the solution file. All changes can be done from your project files. Visual studio Will automaticaly create folders for al target frame works.

Dear @JelteDeJong, with all the respect, but you article feels unfinished.
It contains the good/clear start point "Configuring References for Different Frameworks"..

But in order to "Visual Studio will automatically create folders for all target frameworks" I guess user needs to do some further adjustments which is unclear to anybody who does this for the first time. By default VS places generated DLL to Output Folder and thus overwrites DLL there and you don't tell reader how to escape this and generate files in different folders..

You will need to copy the files to one of the addin folders for Inventor either by doing it manually or by scripting in the postbuilt event, with xcopy command. This is normal best practice.

Dear @bradeneuropeArthur, in fact you don't need to script this - Visual Studio can do this for you a kind of naturally - see the post in my thread.
