无法识别WPF InitializeComponent

Question

完全不熟悉WPF，并且遵循Microsoft演练，该演练要求将XML替换为以下内容：

<Window x:Class="Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Northwind Orders" Height="335" Width="425" 
        Name="OrdersWindow" Loaded="Window1_Loaded">
    <Grid Name="orderItemsGrid">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="258*"/>
            <ColumnDefinition Width="161*"/>
        </Grid.ColumnDefinitions>
        <ComboBox DisplayMemberPath="OrderID" ItemsSource="{Binding}"
                  IsSynchronizedWithCurrentItem="true" 
                  Height="23" Margin="92,12,37.703,0" Name="comboBoxOrder" VerticalAlignment="Top"/>
        <DataGrid ItemsSource="{Binding Path=Order_Details}"  
                  CanUserAddRows="False" CanUserDeleteRows="False"  
                  Name="orderItemsDataGrid" Margin="34,46,34.4,49.6"
                  AutoGenerateColumns="False" Grid.ColumnSpan="2">
            <DataGrid.Columns>
                <DataGridTextColumn  Header="Product" Binding="{Binding ProductID, Mode=OneWay}" />
                <DataGridTextColumn  Header="Quantity" Binding="{Binding Quantity, Mode=TwoWay}" />
                <DataGridTextColumn  Header="Price" Binding="{Binding UnitPrice, Mode=TwoWay}" />
                <DataGridTextColumn  Header="Discount" Binding="{Binding Discount, Mode=TwoWay}" />
            </DataGrid.Columns>
        </DataGrid>
        <Label Height="28" Margin="34,12,0,0" Name="orderLabel" VerticalAlignment="Top" 
               HorizontalAlignment="Left" Width="65">Order:</Label>
        <StackPanel Name="Buttons" Orientation="Horizontal" HorizontalAlignment="Right" 
                    Height="40" Margin="0,261,22.4,4.6" Grid.ColumnSpan="2">
            <Button Height="23" HorizontalAlignment="Right" Margin="0,0,12,12" 
                Name="buttonSave" VerticalAlignment="Bottom" Width="75" 
                    Click="buttonSaveChanges_Click">Save Changes
            </Button>
            <Button Height="23" Margin="0,0,12,12" 
                Name="buttonClose" VerticalAlignment="Bottom" Width="75" 
                    Click="buttonClose_Click">Close</Button>
        </StackPanel>
    </Grid>
</Window>

所以我替换了它，但现在如果我转到文件MainWindow.xmal.cs，InitializeComponent();的代码将突出显示为不存在。

为什么会出现这种情况?我如何纠正它？

您必须将XAML中的x:Class="Window1"与类class MainWindow后面的代码相匹配。

将XAML从x:Class="Window1"更改为x:Class="NorthwindClient.MainWindow"
