</Application>启动页不唯一怎么办？
我们知道设置启动页有两种方式
- 添加窗口
生成操作设置为ApplicationDefinition - 添加cs代码文件，Main方法中运行窗口
但是用以下代码的方式创建窗口，设置的全局样式是不生效的，只有通过StartupUri="Wins/Welcome.xaml"设置启动页才能使全局样式生效
public partial class MyApp : Application
{
public static LoadDialog myloading;
[STAThread]
private static void Main()
{
StopSameProcess();
new MyApp();
}
public MyApp()
{
Run(new LoginWindow());
}
}但是通过StartupUri只能设置唯一的启动页，怎么办呢？
我们可以添加一个欢迎页面作为中间页面，这个页面再决定跳转到那个页面，这样设置的全局样式就生效了。
