.NET 中的配置问题，读取 json 文件时出现问题（我使用的是最新版本的移动开发框架）

Question

当我尝试添加 JSON 文件 via.AddJsonFile() 时，它抛出一个：

System.IO.FileNotFoundException: 'The configuration file 'appsettings.json' was not found and is not optional. The expected physical path was '/data/user/0/com.companyname.rakeshproj/files/appsettings.json'.'

此外，我尝试设置基本路径，但没有帮助，可以推测 Android 系统安全。截图：

作为Microsoft.Extensions.Configuration方法暂时不行，正在考虑中，但最早用于.NET 7：https://github.com/dotnet/maui/issues/4408

如果您想从应用程序包中读取文件，请执行以下操作：

将文件添加到您的 Resources\Raw 文件夹
确保构建操作设置为 MauiAsset
阅读下面的文件内容并根据需要进行操作:)

using var stream = await FileSystem.OpenAppPackageFileAsync("foo.json");
using var reader = new StreamReader(stream);
var fileContent = reader.ReadToEnd();

// For example deserialize JSON here.
