c# - 在 .NET 4.0 中加载存储为 XAML 的工作流

Question

加载以前创建并存储为 XAML 的 .NET 4.0 Beta2 工作流的语法是什么。

WorkflowElement 和 WorkflowXamlServices 类不再存在。我正在尝试做这样的事情（在 Beta 1 中有效）：

WorkflowElement wf = WorkflowXamlServices.Load(File.OpenRead("Workflow.xaml")) as WorkflowElement;

Answer 1

Found my own answer after further research.

The WorkflowElement and WorkflowXamlServices classes have been removed from Beta2. The approach above requires the use of DynamicActivity and ActivityXamlServices.

DynamicActivity wf = ActivityXamlServices.Load("Workflow.xaml") as DynamicActivity;
