 ## Remarks
 
- This switch was for the time before the new, standardized, way of consuming the C++ Standard Library as modules described in [Import the C++ standard library using modules](../../cpp/tutorial-import-stl-named-module.md) was available. Although you can use this switch to use the older experimental named modules, we recommend that you use the new, standardized, way of consuming the C++ Standard Library as modules described in [Import the C++ standard library using modules](../../cpp/tutorial-import-stl-named-module.md).
