Thank you for installing the C/C++ extension! We're excited to announce the following features in the March update:
IntelliSense caching
- On Windows and Linux, the extension will now cache header information to improve IntelliSense speed for your code files. Support for macOS will be available in a future release.
+ The extension will now cache header information to improve IntelliSense speed for your code files.
Please Note: The extension writes the cache to disk in order to achieve this performance improvement. By default the cache files will be stored in your workspace
folder's ".vscode" folder, but you can change this location by using the
"C_Cpp.intelliSenseCachePath" setting. You can also control how much disk space can be
