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.其实我一直觉得寒光四溢、削铁如泥的宝剑该有多厉害，现在才知道这种剑竟然是最低级的，后面还有软剑、重剑、木剑、无剑。全男系音乐剧系列男校风云，是基情满满的友情还是友达以上的爱情呢？In web development, Picture preloading is a common technique, If you set the src attribute directly to the img tag node, If the picture is larger, Or if the network speed is relatively slow, Before the picture is loaded, The picture will be a blank scene for a period of time.
