/* Introduction:
    1. The two DoWork methods  will be invoked in the same thread. A LocaDatStoreSlot is used to share data between them.
    2. In the DoWork method of BusinessLogicClass,  a LocalDataStoreSlot is created and the instance of ApplicationSession is stored in the slot.
    3. In the DoWork method of AnotheBusinessLogicClass, the data stored in the named LocalDataStoreSlot is retrieved.

今天领到了浦发银行的信用卡奖品：捷安特(Giant)自行车一辆。
感觉很满足。乘着手机有点，赶紧打电话跟MM分享了一下。

每次打浦发客服电话，对方态度都很好。
目前我所接触的所有银行中浦发银行客服做的最好。

原来在原图后面有一张微软企业级数据中心系统架构图,正常情况下看不出来,只有在拖动或者页面切换的瞬间可以看出.(后来还发现,还有一张扬声器状物体的图,在图3中可以看出)通过瞬时拷屏技术,将它弄了出来,不过这些东东实的不是很懂.迎大家转载讨论.
