I believe you're looking for Hawkeye. You may also look at GitHub for a more recent version.
WinForms Spy is a good one. The codeproject version doesn't have a draggable cross hairs but there is a version out there that added it.
Try the nuget package: WinForm.Inspector.Tool
Setup documentation
Instantiate the Inspector in your project.
Inspector inspector = new Inspector();
Ignore specific controls ex. buttons.
inspector.IgnoreTypes = new Type[] { typeof(Button) };
Skip controls ex. invisible and disabled.
inspector.SkipChilds = GetChildAtPointSkip.Invisible | GetChildAtPointSkip.Disabled;
Run your project and press Ctrl + F8 to open the ControlViewer.
Hold down "Alt" and move your mouse over the controllers to select them.
