Eslint-plugin-vue: plugin:vue/vue3-essential includes rule "vue/no-v-model-argument" ?

[BoBoooooo]

Here's my config
``` eslintrc.js
module.exports = {
root: true,
env: {
node: true,
},
extends: [
'plugin:vue/vue3-essential'
],
parserOptions: {
ecmaVersion: 2020,
},
rules: {
'no-console': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
'no-debugger': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
},
};

``` package.json

{
  "name": "test",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {

}

When i use like " v-model:propName " in vue 3.x , eslint prompt this error ...

Thank you for this issue.

However, the vue/no-v-model-argument rule is not included in vue3-essential.
https://github.com/vuejs/eslint-plugin-vue/blob/v7.0.0-beta.4/lib/configs/vue3-essential.js

The warning displayed in your image is a warning displayed by Vetur, so it may be a Vetur problem.
(The gray eslint-plugin-vue warning on VS Code is the warning that Vetur is outputting. The warning output by vscode-eslint is displayed as eslint.)

As a workaround, you can also turn off the validation of eslint-plugin-vue built into Vetur.

@ota-meshi Thank you for your answer , I figure it out .

a. when I open vue3 project in VS Code by workspace with another vue2.x project , this warning displayed .
b. but When I open it in single window , everything is fine ..

as you said , it may be a Vetur problem or VSCode problem . anyway thank u !
