| Type                                                                       | Description |

using System.Collections.Generic;
using UnityEditor;
using UnityEditor.VersionControl;
using UnityEngine;

public class EditorScript : MonoBehaviour
{
    [MenuItem("Version Control/Lock")]
    public static void ExampleLock()
    {
        AssetList assets = new AssetList();
        assets.Add(Provider.GetAssetByPath("Assets/ExampleAsset.cs"));
        Task t1 = Provider.Checkout(assets, CheckoutMode.Exact);
