c# - ExecuteAsync 在 Xamarin 中挂起，相同的代码在控制台应用程序中运行良好

Question

此功能适用于控制台应用程序：

private async Task TestAsync()
        {
            var client = new RestClient("https://weatherbit-v1-mashape.p.rapidapi.com/current?lang=en&lon=%3Crequired%3E&lat=%3Crequired%3E");
            var request = new RestRequest(Method.GET);
            request.AddHeader("x-rapidapi-host", "weatherbit-v1-mashape.p.rapidapi.com");
            request.AddHeader("x-rapidapi-key", "d6c6-omitted");
            IRestResponse response = await client.ExecuteAsync(request).ConfigureAwait(false);
            return;
        }

但是当在 xamarin 应用程序中运行时，此代码从未完成执行。任务被调用，但从未完成。与我尝试过的所有其他请求相同。

这是更多代码：

class Program
    {
        static void Main(string[] args)
        {
            var x = TestAsync().Result;
            int y = 0;
        }

        private static async Task<IRestResponse> TestAsync()
        {
            var client = new RestClient("https://weatherbit-v1-mashape.p.rapidapi.com/current?lang=en&lon=%3Crequired%3E&lat=%3Crequired%3E");
            var request = new RestRequest(Method.GET);
            request.AddHeader("x-rapidapi-host", "weatherbit-v1-mashape.p.rapidapi.com");
            request.AddHeader("x-rapidapi-key", "d6c61a25cfmshfc1caea2f83287fp1e287cjsn695b47d979fb");
            IRestResponse response = await client.ExecuteAsync(request);
            return response;
        }
    }

这工作正常，但以下不起作用：

public partial class App : Application
    {

        public App()
        {
            InitializeComponent();


            var x = TestAsync().Result;
            int y = 0;

            DependencyService.Register<MockDataStore>();
            MainPage = new AppShell();
        }

        private static async Task<IRestResponse> TestAsync()
        {
            var client = new RestClient("https://weatherbit-v1-mashape.p.rapidapi.com/current?lang=en&lon=%3Crequired%3E&lat=%3Crequired%3E");
            var request = new RestRequest(Method.GET);
            request.AddHeader("x-rapidapi-host", "weatherbit-v1-mashape.p.rapidapi.com");
            request.AddHeader("x-rapidapi-key", "d6c61a25cfmshfc1caea2f83287fp1e287cjsn695b47d979fb");
            IRestResponse response = await client.ExecuteAsync(request);
            return response;
        }

        protected override void OnStart()
        {
        }

        protected override void OnSleep()
        {
        }

        protected override void OnResume()
        {
        }
    }
