The Microsoft Windows Presentation Foundation (WPF) provides the foundation for building applications and high-fidelity experiences in Windows Vista, blending together application UI, documents, and media content. WPF contains two data sources for XML and objects. To enhance productivity and include WPF applications in lines of business, you need to employ best practices and guidelines in reusing existing internal frameworks through WPF data binding capabilities. That way enterprises will benefit from advanced accessibility, data-driven UIs, and the highly stylized data visualization inherent to the WPF platform.
