.NET Framework Developer Center

.NET Framework Developer Center

Windows Communication Foundation is a part of the .NET Framework that provides a unified programming model for rapidly building service-oriented applications that communicate across the web and the enterprise. 

WCF and WF in .NET 4

In the .NET Framework 4, there have been significant enhancements in the Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF) namespaces. .NET developers can use these technologies, either independently or together, to eliminate the tradeoff between ease of service authoring and performant, scalable services. Read more about WCF and WF in .NET 4.

Windows Presentation Foundation

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 Workflow Foundation Provides a programming model, in-process workflow engine and rehostable designer to implement long-running processes as workflows within .NET applications

Windows Azure platform AppFabric

AppFabric Access Control
AppFabric Access Control Service takes the pain of authentication and authorization out of your web applications and services. A simple and familiar programming model keeps your code clean and allows you to transition to the declarative model of rules and claims. These rules can be easily configured to meet your applications’current and future access control needs. AppFabric Access Control is based on a claims-based authorization model, which alleviates the need to develop and support a variety of identity providers and architectures.

AppFabric Service Bus
AppFabric Service Bus alleviates the pain to expose application's or service’s functionality across a variety of network-related constraints. Once AppFabric Service Bus has established connectivity among applications, it provides flexibility on how applications can communicate with each other. Developers are enabled to build solutions with various communication patterns such as relayed, buffered, bidirectional, publish-subscribe, multicast, streaming and direct-connect. AppFabric Service Bus provides each service a stable Internet-accessible Uniform Resource Identifier (URI) that can be accessed by any authorized client application. Powered by AppFabric Access Control, AppFabric Service Bus is able to control services accessibility with heterogeneous identity systems.
