Hello, I’m using Inventor 2025 and have an add-in project built with .NET 8. I converted the PackAndGo example code from this article: https://adndevblog.typepad.com/manufacturing/2013/05/use-packandgo-of-2014-api.html to C# and tried to use it in my add-in. However, when assigning the ProjectFile property, I get the following error: {"Error HRESULT E_FAIL has been returned from a call to a COM component."} The same code works without issues in a Windows Forms app built with .NET Framework 4.7.2. Any advice or experiences would be appreciated. Thanks in advance!
