Step by Step Solution Structure for ASP.NET MVC Project with EF, MVVM and Repository Pattern

The ASP.NET MVC web application framework which is based on Model-View-Controller provides a designing pattern integrating the principle of SoC (Separation of Concerns). This is mainly a modular approach to design and separating the information that is essential to perform a particular functionality of the computer program within the module which is responsible for the concern.

The Model portion of doing any ASP.NET MVC online Training is implemented through C# classes that defines different properties and methods of the data objects controlled by the application. These class objects are referred to as entities when they are instantiated. They are also referred to as POCO’s (Plain-Old Class Objects) as each object is just a C# Class.

Now, the Model-View-ViewModel that is MVVM design pattern differentiates the models that represent the data objects of ASP.NET MVC project as per the conceptual form from the implementation of the model classes used to create Views and to perform CRUD (Create, Retrieve, Update, and Delete) operations on different data entities. The View model mainly reflects the necessities of the View rather than any conceptual objects which are being affected by the View.

Entity Framework is an object-relational mapper (ORM) which provides another layer of SoC by preparing an interface between persistent storage of data in a Relational Database (RDB) and the model objects of the MVC Framework. The developers can easily write class objects as EF enables Code First Database design which can be translated into SQL data definition language (DDL) that will ultimately create and modifies the underlying database to keep the data store in sync with the Model through migrations. Entity Framework mainly added to the ASP.NET MVC project through NuGet package.

The Repository pattern of designing model separates the logic that stores and retrieves data from business logic which are working on the data. Through this, a developer can get numbers of benefits including elimination of any duplication of code and assisting testing. Repository pattern in web application facilitates the writing of short and well defined Controller actions to act on the data types of objects.

Structuring the Solution:

Now, if all code can be incorporated in one ASP.NET MVC project, the project directory will include the folders and files for:

Also, you will get additional fi8les for application startup, configuration, fonts, routing, scripts, and style sheets (CSS) and utility classes. So, any changes made in one area, the code for the whole section has to be redeployed. Using any separate projects on ASP.NET MVC solution, the developers can also create a greater separation of concerns and integrate the development, debugging, testing and deployment process. Different Layers of Web Applications can be divided into projects as follows:

There are some more complex solutions which can have separate projects for financial transactions, logging and other functionalities. So, to work on multiple projects, ASP.NET provides selective loading of projects for solutions up to 30 projects.

Angular JS Online Training Angular JS is an open-source front-end Javascript framework.It is mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications. Its goal is to augment browser-based applications with Model-View-Controller (MVC) capability and reduce the amount of JavaScript needed to make web applications functional. It’s a structural framework for dynamic web apps. With Angular JS, designers can use HTML as the template language and it allows for the extension of HTML’s to convey the application’s components effortlessly. It has fast-performing features. It also helps to create an interactive Single Page App (SPA) which offers terrific user experience. Angular online training has been designed to help in creating web applications and deploy Angular CLI, Angular components, typescript, bootstrap and many more. Angular JS course provides a platform to learn to design web appli…

What is Web API? ASP.NET Web API is a framework which makes it easy to build up the HTTP services to reach towards the broad range of clients including desktop browsers, any operating systems and mobile devices as well.ASP.NET MVC 5 with Web API is the perfect platform for building RESTful applications on the .NET Framework and uses PUT, GET, POST, DELETE verbs of client communications. When any developers are building APIs on Web, there are so many ways that they can build APIs on the Web including HTTP/RPC that means using HTTP in Remote Procedure Call to call into things like Methods across the Web.
Let’s Start with Web API: First, create a new ASP.NET MVC 5 project and select the Web API template. While selecting the WEB API template, if you want you can change the “Authentication” type to the most suitable one for you. You can keep this as “No Authentication” also and open it as anonymous users. Now, if you are trying to run any project without changing it, you would able to see the…
