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?

Hi Jasper,

The problem happens when creating a brand new C++ "Empty Project", but I can only recreate it on my laptop... My desktop PC works normally with the exact same project file, so I don't expect you to face any issues with the one I am attaching. Furthermore, the COBIA_CodeGen.exe CLI tool seems to work normally, which makes me suspect that something related to my Visual Studio (or plugin) installation is corrupted.

In the meantime, could you please verify that this is the proper way to use the Cobia_CodeGen CLI tool to create e.g. a Unit Operation?

Code: Select all

COBIA_CodeGen.exe /i 'C:\Program Files (x86)\Common Files\CAPE-OPEN Laboratories Network\COBIA IDL\CAPEOPEN_1_2.CIDL' /i 'C:\Program Files (x86)\Common Files\CAPE-OPEN Laboratories Network\COBIA IDL\CAPEOPEN.CIDL'
COBIA_CodeGen.exe /n /P /c "myunit" /o "test.cpp" +name "myunit" +description "test" +capeVersion "1.2" +about "about" +catID "CAPEOPEN::UnitOperation"
COBIA_CodeGen.exe /e "CobiaEntryPoints.cpp"

Thanks for taking the time to look into this.
