Windows Communication Foundation WCF, servis-yönelimli mimariyi temel alarak dağıtık-uygulamalar geliştirmek için kullanılan, dağıtık mimari modelleri ve teknolojileri tek çatı altında birleştiren ve içerisinde bir çok hazır bileşen barındıran bir Framework API‘sidir. (Bknz. Service Oriented Architecture)

Ayrıca WCF mimarisi, .NET Remoting, XML Web Servisleri, Web Service Enhancements (WSE), Enterprise Services/COM+ ve Microsoft Message Queue(MSMQ) gibi bir çok dağıtık uygulama geliştirme modelinin tek bir programlama modeli içerisinde geliştiriciye sunmaktadır.
