嗨，在上面的代码中，使用 Visual Studio android 模拟器根本不显示图像。它在 Windows 应用程序上运行良好。
该页面运行良好，但突然停止。我试图用一个图像标签创建一个新项目，但图像仍然没有显示在 android 模拟器上。
我修复/卸载/安装了Visual Studio Community 2015，但仍然没有显示。
我还删除了hyper v图像，卸载而不是重新安装hyper v，但仍然没有运气
我还尝试使用后面的代码加载图像，如下所示：
img.Source = new UriImageSource
{
Uri = new Uri("http://lorempixel.com/1920/1080/city/1/"),
CachingEnabled = false,
CacheValidity = TimeSpan.FromHours(1)
};
还是不显示！
注意：我可以从模拟器浏览器导航到图像路径
我正在将 Windows 10 与 Visual Studio Community 2015 一起使用。
有人面临同样的问题吗？解决办法是什么 ？
更新：我检查了调试输出，我得到了以下信息：
