TechWorld is reporting that Microsoft plans to move graphics outside of the Windows Vista kernel by pulling the Windows Presentation Foundation (WPF, formerly codenamed "Avalon") out of the Vista kernel. We asked Microsoft for clarification. Here's the official statement: "Because WPF is largely written in managed code on the common language runtime, it never ran in kernel mode. There are elements of WPF (called the MIL) that are written in unmanaged code, but that code also largely runs (and always has run) in user mode. Insofar as WPF needs to touch kernel mode stuff (e.g., drivers), it interacts with them through the existing DirectX APIs. The user mode and kernel mode aspects of the WPF architecture haven't changed," a Microsoft spokesman told us. And nothing has changed in terms of Microsoft's plans for delivering WPF as an integrated part of Vista, the spokesman added.
