服务器没有提供可能由此引起的有意义的回复合同错误，过早的会话关闭或内部服务器错误

嘿，我在调用wcf服务后遇到异常。我知道这个异常可以在stackoverflow上找到很多，但我有一个特殊的行为。我也尝试了几乎所有推荐的解决方案，但没有成功......

我的项目执行以下操作：模块类似于正常聊天，wpf和asp usercontrol每5秒调用一次服务并获取在线用户。这通常在我的Windows 7工作站上正常工作。在我开始使用win 8在我的新工作站上开发软件之后，我得到了这个例外。 IIS配置仍然相同。在第一个用户开始频繁调用服务后，一切正常，直到第二个用户调用相同的服务，上面的异常显示出来。我在win 7上设置了一个测试机，看看会发生什么......一切都有效......我不知道该怎么办......

有没有人有任何想法。令我疯狂的是，该服务适用于第一个正在调用它的用户，但在第二个用户调用它之后，该死的东西不再起作用了...... 请帮忙... THX
