当我使用dot Net MS Graph SDK获取自己的用户信息时出现错误代码406？

这是我的代码，基本上所有代码都是从Microsoft文档样本代码复制而来的：

private async static void exec()
{
    try
    {
        var clientId = "soemid here";
        var tenantID = "some id here";

        string[] scopes = new string[] { "User.Read"};
        
        var email = "[email protected]";
        System.Security.SecureString password = new System.Security.SecureString();
        password.AppendChar('x');
        ... 
        // append whole password here
        password.AppendChar('x');

        IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
         .Create(clientId)
         .WithTenantId(tenantID)
         .Build();

        UsernamePasswordProvider authProvider = new UsernamePasswordProvider(publicClientApplication, scopes);

        GraphServiceClient graphClient = new GraphServiceClient(authProvider);
           
        User me = await graphClient.Me.Request()
                        .WithUsernamePassword(email, password)
                        .GetAsync();

        Console.WriteLine(me.Id);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
    }

    Console.ReadKey();
}

这个问题是什么也没打印，而是我收到了406错误代码。我该如何解决？
顺便说一句，Microsoft 406的文档中的含义是该服务不支持Accept标头中请求的格式。

对于此问题，我会在您的身边使用相同版本的Microsoft.Graph（Microsoft.Graph.Beta -Version 0.19.0-preview）对其进行测试。但这对我来说很好用，因此我在下面提供我的代码供您参考。

using Microsoft.Graph;
using Microsoft.Graph.Auth;
using Microsoft.Identity.Client;
using System;
using System.Security;
using System.Threading.Tasks;

namespace ConsoleApp22
{
    class Program
    {
        static async Task Main(string[] args)
        {
            Console.WriteLine("Hello World!");

            var clientId = "xxx";
            var tenantID = "xxx";

            string[] scopes = new string[] { "User.Read" };
            var email = "xxx";
            
            var str = "xxx";
            var password = new SecureString();
            foreach (char c in str) password.AppendChar(c);

            IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
                 .Create(clientId)
                 .WithTenantId(tenantID)
                 .Build();

            UsernamePasswordProvider authProvider = new UsernamePasswordProvider(publicClientApplication, scopes);

            GraphServiceClient graphClient = new GraphServiceClient(authProvider);

            User me = await graphClient.Me.Request()
                                .WithUsernamePassword(email, password)
                                .GetAsync();

            Console.WriteLine(me.Id + "===" + me.DisplayName);
        }
    }
}
