Question

我是C＃的新手，但多年以前还是一名程序员。我“玩过”游戏并进行了大量搜索以了解这里出了什么问题：

<Window x:Class="WpfApp1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:WpfApp1"
    mc:Ignorable="d" 
    Title="MainWindow" Height="450" Width="800" Margin="0">
    <Grid>
        <Border>                    <-- any time this is here
            <Grid.Resources>        <-- this gets XLS0415 + XDG0012
                ...
            </Grid.Resources>
            <Grid.RowDefinitions>   <-- this gets XLS0415 + XDG0012
                ...
            </Grid.RowDefinitions>
                <Border>                      <-- any time this is here
                    <Grid.ColumnDefinitions>  <-- this gets XLS0415 + XDG0012
                        ...
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>     <-- this gets XLS0415 + XDG0012
                        ...
                    </Grid.RowDefinitions>
                </Border>
            </Grid>
        </Border>
    </Grid>
</Window>

其中：
XLS0415 = The attachable property 'Resources' was not found in type 'Grid'.
XDG0012 = The member "Resources" is not recognized or is not accessible.
和RowDefinitions和ColumnDefinitions相同。

似乎只有InteliSense可以识别<Border>，而XAML解释器（或任何它称为的东西）却不能。
我试图以我能想到的任何方式移动/修改<Border>语句，剪切并粘贴了3个工作示例-总是遇到相同（或相似）的问题

<Grid.Resources>和<Grid.RowDefinitions>标签指出正在将Resources和RowDefintions添加到Grid。因此，<Grid.Resources>和<Grid.RowDefinitions> properties 只能嵌套在<Grid>标记内。定义这些属性后，请定义嵌套的 children元素[s] ，例如<Border>

<Window x:Class="WpfApp1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:WpfApp1"
    mc:Ignorable="d" 
    Title="MainWindow" Height="450" Width="800" Margin="0">
    <Grid>
        <Grid.Resources>
                ...
        </Grid.Resources>
        <Grid.RowDefinitions>
                ...
        </Grid.RowDefinitions>
        <Border> 
            <Grid>
                <Grid.ColumnDefinitions> 
                        ...
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                        ...
                </Grid.RowDefinitions>
                <Border>

                </Border>
            </Grid>
        </Border>
    </Grid>
</Window>

WPF <border>似乎无法识别并导致错误
