To further our investments in WPF, we put out a couple of Open Source Projects to fill in the gaps in the Platform and Documentation.

DirectX Extensions

WPF DirectX Extensions allow you to easily host DirectX 10 and DirectX 11 content in WPF applications. This project is hosted here

WPF Samples

Samples that demonstrate the API usage patterns and popular features for the Windows Presenation Foundation in the .NET Framework for Desktop. These samples were initially hosted on MSDN, and we are gradually moving all the interesting WPF samples over to GitHub. All the samples have been retargeted to .NET 4.5.2. This project is hosted here.
