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.DoS (Denial of Service), its principle is very simple, is to use the machine in our hand to send requests to the server, if the server in our hand has better performance than the server's host in all aspects, then when we send a large number of requests to the server, occupying the server's resources, resulting in the server has no ability to process other user requests.
