Hello!
I’m getting the following errors (in the screenshots) when trying to build the solution in VS 2026. I’m fairly confident I have all the necessary SDK components, and the Rhino VSIX seems to run with no issues. I can build and run C# for Rhino with no issues. Is this an issue with C++ in VS 2026 or is there a new step I’m missing? I’ve done everything the same as I had in VS 2022. Below is the precompiled header code.
Thank you.
