Difference between WPF and WCF

 Windows Presentation Foundation (WPF)
Next-Generation User Experiences. The Windows Presentation Foundation, WPF, provides a unified framework for building applications and high-fidelity experiences in Windows Vista that blend application UI, documents, and media content. WPF offers developers 2D and 3D graphics support, hardware-accelerated effects, scalability to different form factors, interactive data visualization, and superior content readability.


Windows Communication Foundation (WCF)
Windows Communication Foundation (WCF) is Microsoft’s unified programming model for building service-oriented applications. It enables developers to build secure, reliable, transacted solutions that integrate across platforms and interoperate with existing investments.

 In short v can say:

WCF-for( new service oriented attributes,use of interface,callbacks,asynchronous delegates)
WPF-for (styles,templates,animations,databinding,multithreading)
