This article introduces the relevant knowledge of "how to understand the ASP.NET MVC5 website development project framework". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

I. basic framework

Let's talk about the basic framework first. Seven projects look messy at once. My understanding is that among M, V and C, M is the data carrier, V is the attempt that users want to see, C is mainly to coordinate and control the operations related to the user interface, and data processing, database operations to DAL, BLL to do. The whole idea is: View is the interface seen by users; Controller is responsible for coordinating user operations, finding the business logic layer when you need or dealing with data; the business logic layer finds the data access layer when you need to access the database; the data access layer interacts with Sql Server through EF; and the medium for data exchange between layers is Model.

Here IBLL and IDAL are interfaces, and the functions are implemented in BLL and DAL, which may seem superfluous, but it is actually very useful. One is that the interface only implements the method definition and seems clear at a glance; the other is that as long as the interface remains the same, the calls between projects will not change no matter how the implemented code is written.

II. Project establishment

1. Establish Web project.

Select template-> Visual clients-> Web- > ASP.NET Web application.

There is a significant change between here and vs2012, which is in a template made by webform, mvc, api, etc. As shown in the picture

What if you want to develop as before? Click web- > Visual Studio 2012 is not familiar with the feeling back.

Let's choose the Web- > ASP.NET Web application here to confirm.

Choose MVC here (you can choose to add references to webform and api to hodgepodge previous projects together. Select MVC only), select individual user account for authentication, which will add the latest ASP.NET Identity usage code (it doesn't matter what you choose, you don't plan to use ASP.NET Identity here, user management should be done by yourself, and you want to see how Microsoft's code is written).

2. Set up 6 other projects

Right-click on the solution-> add-> New Project

Project type selection-> Visual C #-> Windows- > Class Library.

To build six other projects.

After completion, the framework is as follows:

III. References between projects

Add references between projects after the project is established.

Right-click on the reference to the web project, and select solution-> Project to add references to Ninesky.Models, Ninesky.Common, Ninesky.IBLL, and Ninesky.BLL

In this order: IDAL add Ninesky.Models reference

DAL add Ninesky.Modles, Ninesky.IDAL references

IBLL add Ninesky.Modles reference

BLL adds Ninesky.Models, Ninesky.IDAL, Ninesky.DAL, Ninesky.IBLL references

In addition, DAL Models adds a reference to EntityFramework to the Nuget. The method is to right-click on the project reference and select manage NUGET package. Select online-> nuget.org- > EntityFramework in the pop-up window and click install to complete the installation automatically.

At this point, the framework is finished. Here the web project represents v and c in mvc. The modle project represents m. The common project is ready to write public methods. The other four projects can be regarded as data access layer and business logic layer in the three-tier architecture, in addition, interface-oriented is still used.
