ASP.NET Core MVC中Microsoft Graph客户端类型加载异常求助

背景说明 #

• 最初计划使用graphClient.Me.GetAsync()获取Entra用户属性
• 更新：需要获取graphClient.Me.GetAsync()无法返回的属性，因此改用以下代码：

  var result = await graphClient.Users["{user-id}"].GetAsync((requestConfiguration) => { requestConfiguration.QueryParameters.Select = new string []{ "displayName","givenName","postalCode","identities" }; });
  

  怀疑该功能仅支持Microsoft.Graph 5.61版本，但不确定

错误信息 #

在Visual Studio中运行项目，输入Entra凭据后抛出异常：

处理请求时发生未处理的异常。

TypeLoadException: 无法从程序集'Microsoft.Graph.Core, Version=3.1.22.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx'加载类型'Microsoft.Graph.IAuthenticationProviderOption'。

// 添加Graph API客户端
builder.Services.AddMicrosoftGraph(options =>
{
    options.Scopes = "User.Read"; // 确保此范围已在Azure门户中授予
});

builder.Services.AddControllersWithViews();

var app = builder.Build();

请问我哪里操作有误？已经尝试过更换包版本、修改Program.cs中的代码，但问题仍未解决。
