Wrong _MSC_VER

Reproduce el informe con el c_cpp_properties.json, compilerPath, la cadena de herramientas de VS 2022 y main.cpp proporcionados, y compara después el _MSC_VER mostrado por la extensión con el valor esperado por el compilador. Usa el registro de diagnósticos de C/C++ para rastrear la detección de los valores predeterminados del compilador; se considera terminado cuando la configuración de VS 2022 informa 1944 en lugar de 1951.

Environment

• OS and Version: Windows 10 22H2
• VS Code Version: 1.133.0
• C/C++ Extension Version: 1.32.2

Bug Summary and Steps to Reproduce

Bug Summary: _MSC_VER displayed as 1951 when using VS2022, expected value: 1944.
