　　每年都会推出一部电影的伍迪·艾伦（Woody Allen）又在筹备他的新片了，而这次他要和凯特·温斯莱特（Kate Winslet）合作。现在武侠小说竟然火爆到这种程度。HBO剧集《权力的游戏第八季》将于2019年4月14日播出，本季共6集。胡钧道：我二叔已经死了。李敬文却用不容置疑的口气命令道：那就马上写一个。PS: Many forums have seen beginners ask whether WCF still needs to learn in depth, because they think these technologies may be outdated. Maybe Microsoft will launch a new SOA implementation scheme at that time. Wouldn't it be a waste of time to learn in depth, so they feel that there is no need to learn in depth and just know how to use them. I had the same feeling about this problem before, but now I think that although WCF technology may be replaced, the key to understanding a technology in depth is not to know some more advanced API calls, but to understand its implementation mechanism and way of thinking. Even if the latter technology is replaced, the mechanism behind it is definitely similar. Therefore, if you have a thorough understanding of a technology, you will feel familiar with the new technology and relaxed about it. In addition, after you have a thorough understanding of a technology, you dare to say that you have mastered the technology well during the interview, instead of saying that you use it a lot at ordinary times. Once you ask deeply, you do not know the implementation principle behind it. This is also why I want to write WCF series. I hope this opinion is helpful to some beginners.
