我尝试将 SL 4 应用程序迁移到 SL5 并在编译应用程序时出现以下错误：

Error   17  The tag 'GoToStateAction' does not exist in XML namespace 
'http://schemas.microsoft.com/expression/2010/interactions'.    

Error   31  The type 'GoToStateAction' from assembly 'Microsoft.Expression.Interactions' is built with an older version of the Blend SDK, and is not supported in a Silverlight 5 project.

此错误的 xaml 是： xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions"

   <i:Interaction.Triggers>
                <i:EventTrigger EventName="MouseEnter">
                    <ei:GoToStateAction StateName="ShowStatus"/>
                </i:EventTrigger>
                <i:EventTrigger EventName="MouseLeave">
                    <ei:GoToStateAction StateName="HideStatus"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>

如何解决这个问题？

想通了：为 SL5 安装 Blend Preview。谢谢。
