public static object Deploy() { Contract contract = ContractManagement.Deploy(nef, manifest); return contract.Hash; }}Response body:

Usually, you can define the method _deploy in the contract and execute the neo-cli command deploy contract.nef to deploy the contract.
public static void _deploy(object data, bool update){ if (update) return; // Add other logics after the contract is deployed}
