Handle Resources programmatically

//Add resources.
window.Resources.Add("backgroundBrush", new SolidColorBrush(Colors.Blue));
window.Resources.Add("borderBrush", new SolidColorBrush(Colors.Red));

//Access resources.
Button button = new Button();
button.Background = (Brush)button.FindResource("backgroundBrush");
button.BorderBrush = (Brush)button.FindResource("borderBrush");

How do I create a full-trust XAML Browser Application?

If you want to take advantage of functionality that requires a higher level of trust yet still want
to be integrated into a browser,you can indeed configure an XBAP to require full trust. The
two actions to enable this are a bit convoluted,however:
1. In the ClickOnce application manifest (app.manifest),add Unrestricted=”true” to
the PermissionSet XML element. For example:
<PermissionSet class=”System.Security.PermissionSet” version=”1”
ID=”Custom” SameSite=”site” Unrestricted=”true”/>
2. In the project file (with the .csproj or .vbproj extension),change
<TargetZone>Internet</TargetZone>
to
<TargetZone>Custom</TargetZone>
You can also make this change inside Visual Studio’s project properties UI on the
Security tab.

How to enable our own library to run in the WPF browser application.

You use the same mechanism that applies to all .NET components. If you mark an assembly
with the AllowPartiallyTrustedCallers attribute and install it into the Global Assembly
Cache (which can only be done if the user trusts your code and decides to run it),any of the
assembly’s public APIs can be called by any XBAP

Edit Page: PageFunction

http://msdn.microsoft.com/en-us/library/ms615540.aspx

Below is a simple sample.

PageFunction:

<PageFunction
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:sys="clr-namespace:System;assembly=mscorlib" 
    x:Class="NavigateSample.PageFunction1"
    x:TypeArguments="sys:String"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="300"
    Title="PageFunction1">
    <Grid>

    </Grid>
</PageFunction>

Show page and get result:

//Instantiate the edit page.
PageFunction1 editPage = new PageFunction1();
//Show the page.
this.NavigationService.Navigate(editPage);

//Get returned result.
string result;
editPage.Return += new ReturnEventHandler<string>((object obj, ReturnEventArgs<string> arg)=>
{
    result = arg.Result;
});

Have one Frame Navigate to Another Page

<TextBlock Height="23" HorizontalAlignment="Left" Margin="66,66,0,0" Name="textBlock1" VerticalAlignment="Top" Width="278" >
    Click <Hyperlink NavigateUri="Page2.xaml">Page2</Hyperlink>
    <Hyperlink NavigateUri="Page3.xaml" TargetName="frame">Have frame navigate to another page.</Hyperlink>
</TextBlock>
<Frame Name="frame" Source="Page2.xaml" Margin="66,118,137,52" />
