NET, it is called the "sharing method", because a simple factory is generally only responsible for instantiation. In C #, the static method uses the statics keyword and the Shared keyword in

tools, frameworks that are not yet present, and in the. NET platform only the EntityFramework framework is doing a lot of work for DDD, and if our domain model doesn't map to the database, Then the cost of domain model development will be great.In the design phase, we lack a specific domain-oriented modeling tool, unlike UML, UML is too technical generalization. DDD often bring up the " domain expert " Cor

solve the problem in the origin. But how should we implement it? The solution described in this article is based on a composite control and uses an XML file to define offensive words. We will use VB. NET to compile this composite control, and use a common text editor and command line compiler (vbc) to build the entire project. Before writing controls, let's briefly review the concept of controls in ASP.

RBAC (role access control) can be represented simply by graph, that is, the whole access control process is divided into two steps: access rights and roles, and roles are associated with users, thus realizing the logical separation of user and access rights. Because RBAC realizes the logic separation of user and access rights, it is very convenient for the privilege management. For example, if a user's position is changed, as long as you remove the user's current role and join a role that repre

framework on the net platform has done a lot of work for DDD. If our domain model cannot be mapped to the database, the cost of domain model development will be very high. In the design phase, we lack a modeling tool for specific fields. Unlike UML, UML is too technical and universal. Ddd often mentions 【Field ExpertHe is the most authoritative leader in the field. The UML we created may not be understanda

development level is different, for the architectural design of this abstraction home technology, understanding is different, every time the project started, there are all kinds of controversy, All feel that they are architects, this is very deadly, many people think that design can make development more efficient, code easier to expand, later easier to maintain, better performance, more stable, more easy

(for example, exception handling in VB or C ). However, this goto programming method has affected me for a long time. I still use this programming method when I was studying FORTRAN77 in college. This method is very simple. You don't have to think too much to solve the problem. It also makes me a little rich, so I am too lazy to study other programming methods. Structured Programming is an improvement of noodle code. He first divided the problems t

This is very important because you do not want to retrieve the old content that the user has already viewed. The user should be able to comment on any message, and the posted comment should be displayed directly under the parent message, so as to be clear. In addition, the owner of the network diary should be able to post, edit an

beginning and end. The reason why ASP. NET Web APIs are highly scalable is mainly due to the pipeline design. Although the ASP. NET Web API framework is designed to process requests and respond to requests, the processing policies used vary with specific scenarios. It is impossible and unnecessary to create a "omnipotent" processor to meet all request processing
