Csharp 最小API BindAsync没有'；不工作.Net 6

我试图使用BindAsync手动绑定数据，我遵循了Microsoft的文档，这里有一个链接:Microsoft docs.但这对我不起作用.

我有以下简单的代码

var app = builder.Build();
app.MapGet("/Test",  ([FromQuery] Student student) =>
{
    return  $"Student: {student.Id}, {student.Name}";
}).WithTags("Student");

这是班上的学生

public class Student
 {
     public int Id { get; set; }
     public string Name { get; set; }

     public static ValueTask<Student> BindAsync(HttpContext context, ParameterInfo parameter)
     {
         string name = context.Request.Query["name"];
         int.TryParse(context.Request.Query["id"], out var id);
         var result = new Student
         {
             Name = name,
             Id = id
         };
         return ValueTask.FromResult<Student>(result);
     }
 }

我有两个问题

1. 我收到一个错误，未找到"public static bool TryParse"
2. 即使我像这样在学生课堂上添加简单的TryParse

public static bool TryParse(string value, out Student student)
 {
     student = new();
     return true;
 }

我仍然收到来自端点"Message": "Required parameter "Student student" was not provided from query string."的错误消息，即使我使用swagger发送了它，并且URL是这样的"https://localhost:5001/student?id=7&name=myName"
