(This is the first in an ongoing series about PDC 2008)

While perusing the PDC 2008 website’s preliminary agenda, I came across two sessions that really caught my attention:

Windows 7: Graphics Advances
Windows 7 enables you to advance the graphics capabilities of your applications while carrying forward existing investments in your Win32 codebase, including GDI and GDI+. New enhancements to DirectX let Win32 applications harness the latest innovations in GPUs and LCD displays, including support for scalable, high-performance, 2D and 3D graphics, text, and images. Also learn how to leverage the GPU’s parallelism for general-purpose computation such as image processing.

and

Windows 7: Web Services in Native Code
Windows 7 introduces a new networking API with support for building SOAP based web services in native code. This session will discuss the programming model, interoperability aspects with other implementations of WS-* protocols and demonstrate various services and applications built using this API.

After reading these, I could come to only one conclusion: Microsoft is building an unmanaged version of WinFX (at least the WPF and WCF components of it), currently known as .NET Framework 3.0.

This isn’t the first we’ve heard of this. Long first revealed a job description back in March that related to a new, native UI framework for Windows 7. The PDC session overview doesn’t add much (outside of the WCF component) to what was revealed there, but it does seem to indicate that this framework hasn’t been cut from Windows 7.

A native WinFX excites me for many reasons. One reason is that it opens up the robustness of the Windows Presentation Foundation (WPF) to native developers, most likely with a significant performance gain versus the current managed WPF developers use now.

Also, according to the job description, this framework will use a markup language to define user interfaces (Most likely XAML or something extremely similar), which means designers will be able to use their knowledge (and code) across Win32, .NET and Silverlight now. This could speed adoption of all three technologies, which is nice.

Perhaps the most exciting things to the average user are the possibilities this offers up to Microsoft for Windows 7 itself. Microsoft jettisoned most of its vision for a graphically rich shell when it reset Longhorn development and realized that building Explorer in .NET and on top of a framework that was still in development was a bad idea. Now that this framework (milcore) is done, Microsoft should be able to harness its power rather easily through this new unmanaged WinFX framework without having to completely rewrite Explorer.

In other words, much of the UI goodness from the early Longhorn prototypes could wind up in 7.

Here’s hoping, anyway.
