3D is not rendering in WPF Application

I am trying to render 3D object using the below code. But when I run the application, nothing is displayed. It seems to be blank. Am I missing anything?

<Page x:Class="SampleWpfApplication.DemoPage3"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="126*" />
        <RowDefinition Height="126*" />
        <RowDefinition Height="66" />
    </Grid.RowDefinitions>
    <Viewport3D x:Name="theView3D">
        <Viewport3D.Camera>
            <PerspectiveCamera Position="6,6,6" LookDirection="-4,-4,-4"

I try to render your Viewport3D in WPF application and it's successfully rendered. It shows me a pyramid mesh.

From your code above, you get a blank screen because you are not defining your page height and width.

Here is my solution for your page (Please add your page height and width properties as follow) :

<Page x:Class="SampleWpfApplication.DemoPage3"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    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="DemoPage3" xmlns:my="clr-namespace:SampleWpfApplication">

It appears to render fine for me in Kaxaml.

Perhaps you should try a different machine or use Kaxaml to see if you get any result at all. At this point, it could be any number of things.

EDIT: I noticed that I didn't copy the Grid.RowDefinitions. When I add them, it clips the viewport. If you remove those, does it work?
