.net 3.5下，所有Storyboard都崩溃。怎么回事？

Question

.net 3.5下，有遇到类似的情况吗？总之，编译通过。程序运行立即崩溃。去掉Storyboard，程序运行正常。
而程序在.Net 4.0下，则一切正常，没任何问题。

Answer 1

找到原因了。把下面代码一，改成代码二，即解决了我的问题。.Net3.5，好象不能识别：RoutedEvent="MouseEnter"，只能识别：RoutedEvent="Button.MouseEnter"。代码一
                        <EventTrigger RoutedEvent="MouseEnter">
                            <BeginStoryboard>
                                 ……
                            </BeginStoryboard>
                        </EventTrigger>代码二
                        <EventTrigger RoutedEvent="Button.MouseEnter">
                            <BeginStoryboard>
                                 ……
                            </BeginStoryboard>
                        </EventTrigger>
