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.The function of the intermediary mode is to remove the coupling relationship between objects. After adding an intermediary object, all related objects communicate through the intermediary object instead of referencing each other. Therefore, when an object sends a change, only the intermediary object needs to be notified. Intermediaries loosely couple objects and can independently change their interaction.TopAction: Sweat.
