Introduction to ASP.NET Core WebApp
ASP.NET Core Web Application is a Cloud-Optimized, High-Performance, Cross-Platform, and Open-Source framework for building modern web apps, Internet of Things (IoT), Services, and Mobile Backend can be developed and executed on Windows, Mac, and Linux. The ASP.NET Core executes on .NET Core or on full .NET Framework, and it includes the MVC framework to combine the features of Web API and MVC into a single web programming framework. Moreover, ASP.NET Core consists of modular components with the least overhead, which can retain flexibility while building the solution. In this topic, we are going to learn about ASP.NET Core WebApp.
Create ASP.NET Core WebApp
To create a new ASP.NET Core 3.0 Application in Visual Studio 2019, just open the Visual Studio and select on Create a new Project as shown,
In this “Create a new Project” dialog, there will be various templates of the .NET Core 3.0 Application, each and every template will create predefined project folders and files depending on application type, just create a web application click on the template ASP.NET Core Web Application and click Next as shown below,
Once selecting the application template, just give the suitable name, location for the project; after giving the appropriate name, click on create button as shown below,
Then choose the correct ASP.NET Core Web Application template like Empty, Web, API, MVC Application, and so on. Here we will create the Web Application project, so choose the Web Application template, and then we do not require HTTP’s, so uncheck the Configure for HTTP checkbox and assure that you have selected the correct .NET Core and ASP.NET Core versions. Finally, select on the Create button to create the project.
It creates the new ASP.NET Core Web Project, and Visual Studio takes time to restore the packages in the project. Here the restoring process defines that Visual Studio repeatedly will add, delete or update the configured dependencies as in the project of NuGet Package.
To execute the web application, click on Ctrl+F5 or click on IIS Express. It opens the browser and displays the following as shown,
The above output comes from the Index.cshtml page under the Pages folder.
The output screen displays from the Pages Folder of Index.cshtml page. We can also see through the IIS express icon on the system tray. In your system, ASP.NET sites are executing presently at your development machine; just right-click on it and see, as shown below,
This is the Cross-Platform ASP.NET Core Application which executes on .NET Core.
ASP.NET Core WebApp – Project Templates
ASP.NET Core Web Application is an Open-Source, Cloud-Optimized, High-Performance, Cross-Platform framework for building modern web apps which can be executable on Windows, Mac, and Linux. It includes the MVC framework to combine the features of Web API and MVC into a single web programming framework. The ASP.NET Core executes on .NET Core or on full .NET Framework, and ASP.NET Core consists of modular components with the least overhead instead of this can retain flexibility while building the solution. It was designed to provide the optimized framework for applications deployed to the cloud. By using the ASP.NET Core, we can gain such enhancements as follows,
- Latest tooling which simplifies the new web development
- There is a built-in .NET Core that supports app versioning.
- Create and execute cross-platform ASP.NET apps on Linux, Mac, and Windows. In addition, there will be a single aligned web stack for Web UI and Web APIs.
- Environment based configuration with cloud support
- Built-in support for dependency injection. It facilitates to host on IIS.
In the above example, we can see that the creation of the ASP.NET Core Web Application now; let’s see the creation of the project template; while creating the ASP.NET Core Web Application, we see the various templates of the project.
Let’s discuss a few points about the entire project templates. In this example, we will go to use and build a new ASP.NET Core Web Application using these templates of the project.
Empty Project Template
In the name itself, we came to know that it’s an empty thing that does not have any contents by default, so the Empty Project also, by default there will be nothing in it. If we are required to develop the entire thing manually from scratch, we must select the Empty Template. Look at the following image, which shows the Empty Template,
Web Application (Model-View-Controller) Template
The Web Application (Model-View-Controller) template contains everything that is required to create an ASP.NET Core MVC Web Application. The Web Application (Model-View-Controller) template creates Models, Views, and Controllers folders. It also adds web-specific things such as JavaScript, CSS files, Layout files, etc., which are necessary and required in order to develop a web application. The following image shows the structure of a Web Application (Model-View-Controller) template.
This Web Application (M V C) template contains the entire things that require developing the ASP.NET Core MVC web application. The Web Application MVC template creates the separate folders of Models, Views, and Controllers. This template also includes the desired things we need to design the application like JavaScript, Layout files, CSS files, and so on. Those files are essential to develop the web application with perfection. Let’s see the following image, which shows the template structural format of the web application ( Model- View- Controller ) template.
API Template
API Template contains the entire things required to develop a RESTful service, so API Template is necessary to create an ASP.NET Core RESTful HTTP service. Let’s see the following image below, which shows the structure of the API template,
Look at the above image, which contains only the folder of Controllers. The creation of website essential things like CSS files, View files, JavaScript files, Layout files are not presented in this template. Because an API does not have any user interface, it does not require those files. That API template does not have Views and Models folders because those folders are not required for the creation of API.
Web Application Template
This Web Application template uses the latest Razor Pages Framework for creating Web Applications. Using the latest Razor Pages, the coding page spotlights the situations very easily and gives additional productivity. This template is used only when we want to create a Web Application simple but not with complexity. Let’s see the following image, which shows the structure of the Web Application template,
