C#WPF棱镜页面连接

我尝试使用WPF app.net framework和Prism framework将页面连接到主窗口

我错过了什么

App.xaml：

<prism:PrismApplication x:Class="Aplicatie2._0.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:prism="http://prismlibrary.com/"
             xmlns:local="clr-namespace:Aplicatie2._0">
        <Application.Resources>

        </Application.Resources>
</prism:PrismApplication>

查看->主页：

<Window x:Class="Aplicatie2._0.View.MainPage"
        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:VM="clr-namespace:Aplicatie2._0.ViewModel"
        xmlns:prism="http://prismlibrary.com/"
        xmlns:local="clr-namespace:Aplicatie2._0.View"
        prism:ViewModelLocator.AutoWireViewModel="True"
        
        mc:Ignorable="d"
        Title="{Binding Title}" Height="450" Width="800">
        <Window.DataContext>
                <VM:MainPageViewModel/>
        </Window.DataContext>
        <Grid>
                <ContentControl prism:RegionManager.RegionName="MainContent"/>
                <Button Content="Button" CommandParameter="FirstQ" HorizontalAlignment="Left" Margin="151,54,0,0" VerticalAlignment="Top" Width="75" Command="{Binding PressButton}"/>

        </Grid>
</Window>

窗户是开着的

如果我没有：

 <Window.DataContext>
                <VM:MainPageViewModel/>
        </Window.DataContext>

我错过了什么？

你要么

将名称空间与默认约定对齐（

MyApp.Views

用于视图，

MyApp.ViewModels

用于视图模型）

同时注册视图和视图模型

创建自己的约定以链接视图和视图模型的类型

这样，

ViewModelLocator

就可以完成他的工作

从您发布的代码中，

aplicie2.\u 0.View.MainPage

应该是

aplicie2.\u 0.Views.MainPage

和

aplicie2.\u 0.ViewModel.MainPageViewModel

应该是

aplicie2.\u 0.ViewModels.MainPageViewModel

public MainPageViewModel()

prism:ViewModelLocator.AutoWireViewModel="True"...
