ASP. NET Core what's in the HTTP pipeline? asp. netcorePreface
It's about to end on March 13, 2016. The time is so fast.
After writing the Identity series last time, the response was good, so I was planning to write an ASP. NET Core middleware series, but I encountered a lot of things in the middle. The first is NPOI p
applied over the head, but also in a single project solution without problems, but in. NET multi-project solutions lead to bidirectional dependencies in formal namespaces. Basically, the infrastructure layer has no reuse value as the implementation layer. A better way is to swap the location of the user interface layer and infrastructure layer in the diagram.
You can consider adding the appropriate share layer to the diagram as needed.

Most of us now turn to ASP. NET core to use the development team, should not start from 0 to build the system, but the old business system is already running, ASP.

ObjectiveWith the emergence of micro-services, the management of services is extremely important. All know that microservices are "split", the bloated single-block application, split into a number of lightweight services, each service can be in a short period of time to reconstruct, iterate, delivery. With the increase in the number of micro-services, due to quantitative quality, resulting in a new problem one of which is the management of services. W
ObjectiveAt the beginning of this article, I would like to say two more sentences, but also for the future to never talk about such words.In the daily work, the most contact development work is still on the. NET Core platform, of course, because of the openness of team leadership and the diversity of team style (which is inseparable from the CTO and the supervisor's personal ability), the industry's cutting
built-in security considerations and a good security threat model is meaningless.
From object to Aspect
The object-oriented concept is good at splitting the system into components and describing processes with components. It is also good at processing component concerns. However, the cross-cutting concerns are not object-oriented. Cross-cutting concerns are those that affect multiple components of the system, such as logs, security, and exception handling. The main purpose of AOP orientation is

communicate behavior in a way similar to PRC. In other words, this service exposes a series of fine-grained methods on the presentation layer. The presentation layer must call each other to complete the required operations.
Summary
The service layer is always necessary because it can remove the coupling between the application interface and the middle layer. The only situation that does not consider using the service layer is that you are very sure that the program has only one presentation lay
