asp.net-core – 找不到Swashbuckle.AspNetCore SwaggerOperatio

生成的swagger文档似乎是正确的,除了操作名称不是很好.

"/api/Addresses/{id}": {
      "get": {
        "tags": [ "Address" ],"operationId": "ApiAddressesByIdGet","consumes": [],"produces": [],"parameters": [
          {
            "name": "id","in": "path","required": true,"type": "string","format": "uuid"
          }
        ],"responses": { "200": { "description": "Success" } }
      },

我在许多文章和SwashBuckle.AspNetCore的官方文档中看到我可以使用属性来装饰我的控制器方法,如下所示：

[HttpGet]
 [Produces("application/json")]
 [ProducesResponseType((int)HttpStatusCode.NotFound)]
 [ProducesResponseType(typeof(List<AddressDto>),(int)HttpStatusCode.OK)]
 [SwaggerOperation("GetAllAdresses")]
 public async Task<IActionResult> GetAllAsync()
 {
   ....
 }

不幸的是,我收到了一个错误：无法找到SwaggerOperationAttribute！

我验证了安装的nuget包,它们是：

> SwashBuckle.AspNetCore.Swagger(3.0.0)
> SwashBuckle.AspNetCore.SwaggerGen(3.0.0)
> SwashBuckle.AspNetCore.SwaggerUI(3.0.0)

有人可以帮帮我吗？请
