WPF应用程序中的当前上下文中不存在名称"InitializeComponent"

Question

我已经检查了StackOverflow上的所有类似问题,但没有一个答案解决了我的问题.我只是在标题中得到错误.

这是我的MainVindow.xaml:

<Window x:Class="CodeFirstMVVM.App.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:cm="clr-namespace:System.ComponentModel;assembly=System"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:vm="clr-namespace:CustomerOrder.App.ViewModel"
        xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
        mc:Ignorable="d"
        DataContext="{Binding Source={StaticResource Locator}, Path=CustomerView}"
        Title="MainWindow" Height="500" Width="900">
    <Grid>
        <Canvas>
            <TextBox Height="23" Canvas.Left="131" TextWrapping="Wrap"  Canvas.Top="51" Width="283" Name="txtName" Text="{Binding NameUI}"/>
            <DataGrid x:Name="maingrid" ItemsSource="{Binding Entities, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" SelectedItem="{Binding SelectedEntity}" AutoGenerateColumns="True" Canvas.Left="10" Canvas.Top="265">
                <DataGrid.Columns>
                    <DataGridTextColumn Binding="{Binding Name}" Header="Name" Width="200"></DataGridTextColumn>
                </DataGrid.Columns>
            </DataGrid>
            <DataGrid x:Name="ordergrid" ItemsSource="{Binding ElementName=maingrid, Path=SelectedItem.Orders}" AutoGenerateColumns="True" Canvas.Top="265" Canvas.Left="597">
                <DataGrid.Columns>
                    <DataGridTextColumn Binding="{Binding Explanation}" Header="Orders" Width="200"></DataGridTextColumn>
                </DataGrid.Columns>
            </DataGrid>
        </Canvas>

    </Grid>
</Window>

这是我的App.xaml:

<Application x:Class="CustomerOrder.App.App" 
             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"
             StartupUri="MainWindow.xaml" 
             mc:Ignorable="d">
    <Application.Resources>
        <vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" xmlns:vm="clr-namespace:CustomerOrder.App.ViewModel" />
    </Application.Resources>
</Application>

在MainWindow.xaml.cs上:

namespace CustomerOrder.App
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }
}

你能告诉我怎么解决这个问题吗？谢谢.

要修复它,请更改xaml的命名空间

<Window x:Class="CustomerOrder.App.MainWindow"
