问题
I am writing a C#/XAML Windows Store app and would like to create and navigate to and display a Page entirely from C#. Is this possible? Obviously I can inherit from Page, but, when attempting to Navigate to a derived Page that has no XAML, I get a System.TypeLoadException... "Could not find Windows Runtime type 'Windows.Foundation'".
My thought was this should be possible since XAML translates into a CLR partial class definition, so there's no reason one couldn't do everything in C#. But obviously I missing some sort of framework requirement.
Suggestions?
Right now all I have for the derived Page is
using Windows.UI.Xaml.Controls;
namespace App1 {
public class Page2 : Page {
public Page2 () { }
}
}
And here is the full exception:
Could not find Windows Runtime type 'Windows.Foundation'.
at System.StubHelpers.WinRTTypeNameConverter.GetTypeFromWinRTTypeName(String typeName, Boolean& isPrimitive)
at System.StubHelpers.SystemTypeMarshaler.ConvertToManaged(TypeNameNative* pNativeType, Type& managedType)
at Windows.UI.Xaml.Controls.Frame.Navigate(Type sourcePageType)
at App1.MainPage.<P2>d__2.MoveNext()

I can give an example for a simple page
using System;
using Windows.ApplicationModel.Activation;
using Windows.UI;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Media;
namespace MyApp
{
class Program
{
public static void Main (string[] args)
{
Application.Start((p) => new MyApp());
}
}
class MyApp : Windows.UI.Xaml.Application
{
public MyApp(){}
protected override void OnLaunched(LaunchActivatedEventArgs args)
{
var layoutRoot = new Grid() { Background = new SolidColorBrush(Colors.Blue) };
layoutRoot.Children.Add(new Button() { Content = "Hello!" });
Window.Current.Content = layoutRoot;
Window.Current.Activate();
}
}
}
Replace these paths with the correct items when compiling:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe /target:appcontainerexe /r:"C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Runtime.WindowsRuntime.dll" /r:"C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Runtime.dll" /r:"C:\Windows\System32\WinMetadata\windows.applicationmodel.winmd" /r:"C:\Windows\System32\WinMetadata\windows.ui.winmd" /r:"C:\Windows\System32\WinMetadata\windows.ui.xaml.winmd" /r:"C:\Windows\System32\WinMetadata\windows.media.winmd" MyApp.cs

You can create dynamic XAML using LINQ and XML.
Here's an example on how to create a dynamic TextBlock; you can use the concept to apply it to a Page element:
