打开 VS2022 新建项目 Wpf_Examples创建各层级文件夹安装 CommunityToolkit.Mvvm 和 Microsoft.Extensions.DependencyInjectio NuGet包,完成MVVM框架搭建。搭建完成后项目层次如下图所示 这里如何实现 MVVM 框架可以参考本人 像 MvvmLight 一样使用 CommunityToolkit.Mvvm 工具包 的文章
2、整理项目
1、项目目录层级
在前面该案例前已经发布了两个案例为了后续不断推出的新案例我们先将项目整理成一个整体做成整套案例系统,后续所有的案例都在该项目上迭代更新。目前先做简单的归纳处理我们把所有案例都单独放在一个窗体主窗体做按钮菜单每个案例通过弹窗方式呈现。基于以上整理后得到系统文件层级分布如下所示 2、案例代码实现
1、主界面菜单实现
1、MainWindow.xaml 代码
