Does the vscode-cpptools extension currently support C++20 modules?

C++20 Modules is a great feature, and it's well liked by many. I'm developing a program leveraging C++20 Modules in VSCode, and my code both compiles and runs without any issues. However, the cpptools extension always throws numerous error messages at me, suggesting it can't locate the modules I've defined. My project is built using CMake, and I'm using the latest versions of VSCode, Visual Studio, MSVC, and the vscode-cpptools extension. I'm not sure what's going wrong, as my program compiles and runs perfectly, yet the vscode-cpptools extension consistently flags errors.

I wonder if the vscode-cpptools plugin now supports the C++20 Modules feature? It would be helpful if someone could provide a minimal example of code using the C++20 Modules feature (based on CMake).

@xb284524239 Modules support is still in development, so it has bugs, such as #9965 .

Hearing this news in 2024 is disappointing!

It's September 2025 now, and this issue still hasn't been resolved. It's hard to imagine that even though the C++20 standard has been out for so many years, the support from relevant tools is still experimental.
