Visual Studio for Mac-System.InvalidOperationException：找不到资源：wear-frame-round-390.png

Question

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。在XML编辑器中选择Wear OS Round 390x390作为设备时，尝试在设计模式下查看activity_main.xml时，我收到以下错误。任何想法为什么以及如何解决这个问题？

错误：

我的解决方案中的我的资源文件夹：

我的activity.xml：

<?xml version="1.0" encoding="utf-8"?>
<android.support.wear.widget.BoxInsetLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="@dimen/box_inset_layout_padding" tools:deviceIds="wear">
    <FrameLayout android:layout_width="match_parent" android:layout_height="match_parent" android:padding="@dimen/inner_frame_layout_padding" app:boxedEdges="all">
        <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" />
    </FrameLayout>
</android.support.wear.widget.BoxInsetLayout>
