#Hardhat projects support

Hardhat for Visual Studio Code provides enhanced functionality for Solidity files within a Hardhat project, including inline validation and quick fixes.

To take advantage of these features, use the File menu to Open Folder, and select the folder containing the hardhat.config.{js,ts} file.

Inline validation (the display of compiler errors and warnings against the code) is based on your Hardhat configuration file. The version of the solc solidity compiler used for validation is set within this file, see the Hardhat documentation for more details.
