我正在学习书籍Pro WF Windows Workflow in .NET 3.5，在第5页上，它展示了如何在Visual Studio 2008中打开一个新项目，选择“Visual C#/Workflow”，并显示了8个模板：
- Empty Workflow Project
- Sequential Workflow Library
- SharePoint 2007 State Machine W...
- State Machine Workflow Library
- Sequential Workflow Console Application
- SharePoint 2007 Sequential Workflow
- State Machine Workflow Console Application
- Workflow Activity Library
然而，在我的（德语）Visual Studio 2008中，即使安装了SP1，在工作流程下我只有：
- Sequenzieller SharePoint 2007-Workflow
- SharePoint 2007-Statuscomputerworkflows
在 WCF 下，我发现：
- Sequential Workflow Service Library
- State Machine Workflow Service Library
但是我如何获得书中提到的Visual Studio 2008工作流模板？
