Xamarin.android Visual Studio for Mac-System.InvalidOperationException:未找到资源：wear-frame-round-390.png

我刚刚为Mac安装了最新版本的Visual Studio Community 2019。我正在尝试开发wearOS应用程序。在XML编辑器中选择Wear OS Round 390x390作为设备时，我在设计模式下尝试查看

activity\u main.XML

时收到以下错误。有什么办法解决这个问题吗

错误：

您好，从错误日志中，找不到

wear-frame-round-390.png

，它是否存在于项目的

Resources

文件夹中。@JuniorJiang MSFT否，我已经修改了我的帖子，添加了我的Resources文件夹的屏幕截图。这是在Visual Studio for Mac上新的wearOS应用程序中创建的默认文件。好的，您的意思是新创建的项目在第一次运行时出现错误。不，我没有尝试运行它。这是修改activity_main.axml.OK时的设计视图，您能否共享

activity_main.axml

的屏幕截图？我的下拉列表中的项目与我的屏幕截图中所示的不同。我可以选择分辨率。@Bhav Hi，很抱歉共享图像无效。你可以重新上传，我会检查的。顺便说一句，如果你能选择它并且有后续的，我想它会有用的。我已经上传了。@Bhav抱歉，我只能看到没有有效图像的图像。@Bhav嗨，我已经复制了这个问题。在GitHub中也会发现这是一个问题。虽然它已经在Github关闭，但您也可以在中投票支持它。
