COBIA Class Wizard fails with "No supported projects loaded"

[desyk]

Hello all,

I'm facing a strange issue with the COBIA Class Wizard (with Visual Studio 2026) on my laptop. Every time I try to either add a new class, implement an interface, add entry points, or publish a PMC, it fails with "No supported projects loaded". Any ideas what might cause this?

On my desktop PC with the same versions of Visual Studio and COBIA-SDK the Class Wizard works normally. The issue persists after reinstalling COBIAx64, COBIA-SDK, and the Class Wizard.

Edit: The problem persists even after a repair and a full reinstall of Visual Studio have been performed.

Here's some potentially useful debugging info (same across both computers):
Visual Studio Version: 18.12.0 (previously 18.11.2)
COBIA Class Wizard Version: 1.0.12
COBIA-SDK Version: 1.2.2.1
CAPE-OPEN IDL file creation date: 2026/04/20

Do you have a solution loaded with in there at least one C++ project? Can you share a minimal solution for which you find the wizard does not work?
