In WinFX, a workflow can be expressed in either declarative XAML or in imperative code using any .NET-targeted language. The use of XAML allows for workflows to be developed and modified in visual designers without requiring traditional C# or Visual Basic code. A workflow can be defined either purely in XAML or with XAML plus a codebehind file that contains C# or Visual Basic code.
