【问题描述】：

我使用 VS2008 创建了一个继承自 CompositeActivity 的自定义工作流活动，如下所示

public class CustomWorkflowActivity : System.Workflow.ComponentModel.CompositeActivity

我可以毫无问题地写下面的内容

<GS0:People365WorkflowActivity x:Class="People365.Workflows.Advance_Loan_1WF"
                           x:Name="Advance_Loan_1"
                           xmlns:GS0="clr-namespace:WorkflowEngine.Engine;assembly=WorkflowEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=d2bf1cbcd6bbcd82"
                           xmlns:GS1="clr-namespace:WorkflowEngine.ActivityLibrary;assembly=WorkflowEngine.ActivityLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=d2bf1cbcd6bbcd82"
                           xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<GS1:People365SequenceActivity x:Name="Activity2" WorkflowTemplateActivityId="a6b6327b-c27f-459e-a933-c3cf66ab711f" IsMandatoryActivity="False"></GS1:People365SequenceActivity>
</GS0:People365WorkflowActivity>

将应用程序迁移到VS2010后，出现以下错误

“People365WorkflowActivity”类型不支持直接内容。
类型“WorkflowEngine.Engine.People365WorkflowActivity”没有合适的 TypeConverter 或内容属性来处理此内容。

非常感谢任何帮助。
