您可以尝试使用Microsoft.Extensions.Configuration.AzureAppConfiguration SDK，它将帮助您检测应用配置的更改。
首先安装Microsoft.Azure.AppConfiguration.AspNetCore和Microsoft.Extensions.Configuration.AzureAppConfiguration NuGet包。
下面是示例代码：
Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
    var builder = new ConfigurationBuilder();
    builder.AddAzureAppConfiguration(options =>
    {
        var settings = Configuration.GetConnectionString("AppConfig");
        options.Connect(settings)
               .ConfigureRefresh(refresh =>
               {
                   refresh.Register(key: "SentinelKey", refreshAll: true);
               });
    });
    Configuration = builder.Build();
}

下面的ODE将检测更改：

public void ConfigureServices(IServiceCollection services)
{
    var builder = new ConfigurationBuilder();
    builder.AddAzureAppConfiguration(options =>
    {
        var settings = Configuration.GetConnectionString("AppConfig");
        options.Connect(settings)
               .ConfigureRefresh(refresh =>
               {
                   refresh.Register(key: "SentinelKey", refreshAll: true);
               });
    });
    Configuration = builder.Build();

    ChangeToken.OnChange(
        () => Configuration.GetReloadToken(),
        () => OnConfigurationChanged());
}

private void OnConfigurationChanged()
{
    Console.WriteLine("Configuration has been updated!");
}

另一种方法是使用IOptionsMonitor，它用于检索选项和管理TOptions示例的选项通知。
