Integrating Direct3D with XAML and Windows 8.1 - Direct3D Rendering - page 378

By removing Windows 8.1 specific calls (such as the SharpDX.
DXGI.Device3.Trim method), it is also possible to implement
this recipe using Direct3D 11.1 for Windows Store apps that
target Windows 8.

Rendering to a CoreWindow

The XAML view provider found in the Windows Store app graphics framework cannot be
modified. Therefore, when we want to implement the application's graphics completely
within DirectX/Direct3D without XAML interoperation, it is necessary to create a basic view
provider that allows us to connect our DirectX graphics device resources to the windowing
infrastructure of our Windows Store app.

In this recipe, we will implement a CoreWindow swap-chain target and look at how to hook
Direct3D directly to the windowing infrastructure of a Windows Store app, which is exposed by
the CoreApplication , IFrameworkViewSource , IFrameworkView , and CoreWindow
.NET types.

This recipe continues from where we left off with the Preparing the swap chain for Windows
Store apps recipe.

How to do it…

We will first update the Common.WinRT project to support the creation of a swap chain
for a Windows Store app's CoreWindow instance and then implement a simple Hello
World application.

1. Let's begin by creating a new abstract class within the Common.WinRT project, called

D3DAppCoreWindowTarget and descending from the D3DApplicationWinRT
class from our previous recipe. The default constructor accepts the CoreWindow
instance and attaches a handler to its SizeChanged event.
