Workflow, Communications Improved in .NET 4.5

New versions of the Windows Workflow Foundation (WF) and Windows Communication Foundation (WCF) are available in the .NET Framework 4.5, which is included with Windows Server 2012 and Windows 8. The upgrades improve the developer experience and the manageability of applications built using the foundations, while adding new capabilities. Some benefits, such as WF performance improvements and WCF configuration simplification can be realized for existing applications without requiring developers to make modifications. However, a majority of the enhancements are most helpful when writing new code.

WF 4.5 Brings Better Designer, Versioning

WF offers a specialized programming environment for business processes, called workflows. WF 4.5 improves on the previous version, WF 4, while providing backward compatibility.

WF Simplifies Business Process Programming

WF consists of programming interfaces, design and debugging tools, and a runtime engine (which is separate from the common language runtime included with the .NET Framework) that enable the implementation and execution of workflow processes, reducing the amount of code a developer must write.
