Change default startup page for windows phone 8.1 app
提问by joym8
I created a new Basic Page called PivotPage.xaml in the Windows Phone 8.1 project of the universal app solution. When I go to App.xamlunder the Shared partition, I want to change HubPage in the code below to the newly created PivotPage. But VS refuses to recognize PivotPageas a legitimate type. The namespace of both pages and the class definitions are exactly the same.
我在通用应用解决方案的 Windows Phone 8.1 项目中创建了一个名为 PivotPage.xaml 的新基本页面。当我转到共享分区下的App.xaml 时，我想将下面代码中的 HubPage 更改为新创建的 PivotPage。但是 VS 拒绝识别PivotPage为合法类型。两个页面的命名空间和类定义完全相同。
if (!rootFrame.Navigate(typeof(HubPage), e.Arguments))
{
throw new Exception("Failed to create initial page");
}
If there is any other way to change the default page please let me know that too.
如果有任何其他方法可以更改默认页面，也请告诉我。

Try this
尝试这个
WP 8.1 Universal Project
WP 8.1 通用项目
-> Add New Item -> Blank Page
-> Name it MyPivotPage.xaml
-> 添加新项目 -> 空白页
-> 将其命名为 MyPivotPage.xaml
MyPivotPage.xaml
我的数据透视页.xaml
<Page
x:Class="YOUR_NAMESPACE.MyPivotPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:YOUR_NAMESPACE"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid>
<Pivot Title="MY APPLICATION">
<!--Pivot item one-->
<PivotItem Header="item1">
<Grid/>
</PivotItem>
<!--Pivot item two-->
<PivotItem Header="item2">
<Grid/>
</PivotItem>
</Pivot>
</Grid>
</Page>
Change "YOUR_NAMESPACE" to your namespace :)
将“YOUR_NAMESPACE”更改为您的命名空间:)
Then in App.xaml.cs
然后在 App.xaml.cs
#if WINDOWS_PHONE_APP
if (!rootFrame.Navigate(typeof(MyPivotPage), e.Arguments))
{
throw new Exception("Failed to create initial page");
}
#endif
#if WINDOWS_APP
if (!rootFrame.Navigate(typeof(MainPage), e.Arguments))
{
throw new Exception("Failed to create initial page");
}
#endif
