What is WCF s learning path? How the WCF works

First understand what WCF does, then understand its coding specifications and make an example to turn around.

Then delve into the research and write custom attributes according to the needs of the actual application to solve the actual problem.

Make a list of all the knowledge points and learn and practice them one by one.

The meaning of WCF: The full name of WCF in English is World Cat Federation, and the Chinese translation is "World United Cat Club".

The difference between WCF and CFA of British Short Cats.

One: the difference between organizations.

Founded in 1988 and officially registered in Germany, WCF Chinese translated as "United Cats Club" is a global non-profit organization, and today WCF has more than 370 cat clubs on 5 continents. CFA is the abbreviation of The Cat Fanciers' Association, Chinese translated as "International Cat Lovers Federation", is a non-profit organization registered in the United States, founded in early 1906. To date, CFA has become the institution with the most registered purebred cats in the world.

2. The difference in the competition system.

WCF has set up a professional examination link, breeders bring their own cats to participate in the professional examination to the professional judging room, and the referee face-to-face, one-on-one communication, the referee will focus on all parts of the cat, tell you her advantages and disadvantages, tell the cat is not congenital or in the breeding. Breeders can also ask some questions about the feeding of these cats, as well as questions about the selection of notes, which will be answered by the judges. Communicate with the referee face-to-face and learn.

At the CFA Cat Show, cats compete in four categories: kitten (kitten) between four and eight months old; Adult group, unneutered adult cats of eight months or more; Neutered cat group, neutered adult cats of eight months or more; In the adult and neutered categories, the cats will only be divided into open, champion and super champion categories.

3. The difference between registration service fees.

CFA is $10 per cat, and only a single cat will be allowed to be recorded in the CATS system. It is not possible to request a record for a litter of kittens using the standard whole litter application process. Cats are transferred from CATS to the CFA standard registration system for $20 each.

When a cat has met the standard registration requirements, the cat will not be automatically converted to the CFA standard registration system. The conversion requires an application from the owner of the cat.

The registration fee of WCF is slightly higher than that of CFA, but the registration of a single cat is currently about 150 yuan, and the registration of a whole cat is about 120 yuan per cat!

Different associations, one German, one American.

C is a must to be learned because it is the foundation. But C++ doesn't have to be learned. It is recommended that you first clarify what exactly you want to learn.

It is recommended to do it synchronously.

MVC is a bit difficult, if you use it in a job or internship, it will be quick to learn, and self-study is very boring and obscure. WCF is enough for 3 months, and there is not much content. How proficient you are depends on your ability. I don't expect to score, just say my suggestion.

First of all: the full name of WCF is Windows Communication Foundation, which means Windows Communication Foundation, which is a unified programming model provided by Microsoft for building service-oriented applications. All technologies related to distributed systems under the .NET platform.

Second: WCF is inherently service-oriented. It is mainly divided into two parts: server and client. The process of communication between the server and the client is shown in the following figure

In the diagram above, the host process is the server where the service is created and then the service communicates with the client via an endpoint. When a client uses a service, it needs to first create a service and then call that service.

Endpoints are a very important part of WCF. It contains the address, binding, and contract. The address defines the location of the service, the binding defines how the service communicates, and the contract defines the functionality provided by the service.

For memorization, let's refer to these three elements of an endpoint simply as the ABC of the service

What services are provided by the server and what functions are available, this is called the contract of the WCF service.

WCF services cannot exist in a vacuum. Each WCF service must be hosted in a Windows process, which is called a host process.

The WCF service host can be provided by IIS, by Windows Services, or by Windows Vista's Windows Activation Service. Among them, only the HTTP protocol can be used with IIS hosting.

NET has a wide range of applications, and after learning the estimation language for a year, the framework should be no problem, focusing on learning interfaces, security machines, and WCF (data services), which will be useful for stimulating job hunting in the future. If you are higher, it depends on what you do in the future, the application is very wide, CS (client server mode), BS (browser server mode) have professional needs, portal network, management software, industrial control, etc., different occupational and technical needs are very different, there is time to learn more operating system principles, specific to Windows, or Linux operating system to have an in-depth understanding, when the actual application of NET, you often need to have an in-depth understanding of the principles of Minghui virtual operating system, At this point, language doesn't matter. It is impossible to get familiar with the principles of the operating system, it is too huge, and Biwang will choose it according to the direction of career development in the future.
