我有一个现有的 Blazor 服务器应用程序，可以很好地连接到 Microsoft Entra id 和 Azure SQL 数据库。客户希望为患者创建一个移动应用程序。 blazor 服务器应用程序仅供客户端管理员使用。
我尝试创建一个 .NET 8 MAUI Blazor 混合应用程序（我使用 Jetbrains Rider，因为这是我可以让 Android 和 iOS 模拟器在我的 Mac 上运行的唯一方法）。我几乎遵循了我能找到的所有教程，但没有运气。我什至问过ChatGPT，它给了我很多有用的信息，但仍然不知道该怎么做。
只有一种解决方案打开了 Microsoft 登录屏幕并让我输入密码和身份验证码，但它没有进行身份验证。我也没有收到任何错误。该项目的链接如下。
https://github.com/VladislavAntonyuk/MauiSamples/tree/main/Auth
我尝试了很多不同的解决方案，但我在这里不知所措。我也只有大约 3 个月的时间来构建这个移动应用程序（Android 和 iOS）。
有人可以帮忙吗？我可以给出我所拥有的代码，但它有很多不同的“解决方案”，因此我不会在这里列出任何代码。
更新：这是我从 ChatGPT 获得的一个解决方案，但仍然不起作用，我知道我说过我不会发布代码，因为有很多“解决方案”。这似乎是最深思熟虑的，但仍然存在类似的问题。 “.WithParentActivityOrWindow（MauiApplication.CurrentActivity）//将MainActivity调整为您的实际主要活动”这一行给我带来了问题。它显示“无法解析符号‘CurrentActivity’”（在 Rider IDE 中）。 ChatGPT 最初说使用“MainActivity.CurrentActivity”，但给出了相同的错误。
