Building Your Next Web App with ASP.NET Core

One of the merits of ASP.NET Core is how it manages to provide a number of built-in solutions for different use cases without getting in the way.

In this blog post we take a look at some of these built-in solutions in ASP.NET Core (MVC, Razor Pages, Blazor), what each one is best suited for, and how we could use them to build a fictional supercar.fans app.

Background

ASP.NET MVC was a Ruby on Rails inspired, open-source web framework for .NET, released in 2009. (Fun fact: Scott Guthrie wrote the first few hundred lines of this framework while on a flight) In 2014, the ASP.NET team began rewriting ASP.NET MVC to make it more cloud-friendly, and in the process ended up making it cross-platform. About two years later, in 2016, these were released as ASP.NET Core 1.0, along with the cross-platform .NET Core 1.0

Today, ASP.NET Core is at 3.1 and targets .NET Core 3.1 by default. By targeting .NET Core 3.1, all APIs available in .NET Core 3.1 are made available to ASP.NET Core 3.1 users.

The ASP.NET Core Framework

ASP.NET Core is a web application framework that lays the groundwork for creating web apps in .NET Core. It provides out-of-the-box support for dependency injection, logging, configuration, etc., provides complete control of the request pipeline through its middleware API, and a lot more.

A very basic Hello World application in ASP.NET Core could look like:

public static class Program
{
    public static void Main() =>
        WebHost.CreateDefaultBuilder() // create a webhost builder
            .Configure(app =>
            {
                app.UseRouting();
                app.UseEndpoints(endpoints =>
                {
                    endpoints.MapGet("/", async context => 
                        await context.Response.WriteAsync("Hello World"));
                });
            })
            .Build()           // use the builder to build the webhost
            .Run();            // run the webhost
}

It creates a WebHost, and Configures it to use the routing middleware, and then specifies what to do when a HTTP GET request to / is received.

ASP.NET Core also provides three main higher level frameworks:

  1. MVC
  2. Razor Pages
  3. Blazor

Each of these address different use-cases. And since they are added to the application as middleware, they can easily co-exist in the same application allowing us to use the right tool for the job.

ASP.NET Core MVC

This is very similar to the old ASP.NET MVC in concept.

We have a bunch of controller actions (C## methods) that accept and process HTTP requests, and return Razor views.

Here’s a Hello World example:

// Controllers/HelloWorldController.cs

public class HelloWorldController : Controller
{
    [HttpGet("/")]
    public IActionResult Hello() => View();
}
<!-- Views/Hello.cshtml -->

<p>Hello World!</p>

We can also use MVC without Razor views for APIs. The following example returns a JSON object instead:

// Controllers/HelloWorldController.cs

[ApiController]
public class HelloWorldController : ControllerBase
{
    public IActionResult Hello() => 
        Ok(new { Message = "Hello World" });
}

Writing Web APIs using MVC is a joy. For web pages though, MVC can feel like ceremony despite the flexibility it offers.

If you’re trying to create a Web API, whether for public consumption or for your client applications, MVC is the perfect tool for the job.

jQuery Ajax CRUD in ASP.NET Core MVC with Modal Popup

In this article, we’ll discuss how to use jQuery Ajax for ASP.NET Core MVC CRUD Operations using Bootstrap Modal. With jQuery Ajax, we can make HTTP request to controller action methods without reloading the entire page, like a single page application.

To demonstrate CRUD operations – insert, update, delete and retrieve, the project will be dealing with details of a normal bank transaction. GitHub repository for this demo project : https://bit.ly/33KTJAu.

Sub-topics discussed :

  • Form design for insert and update operation.
  • Display forms in modal popup dialog.
  • Form post using jQuery Ajax.
  • Implement MVC CRUD operations with jQuery Ajax.
  • Loading spinner in .NET Core MVC.
  • Prevent direct access to MVC action method.

Create ASP.NET Core MVC Project

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N).

From new project window, Select Asp.Net Core Web Application_._

Image showing how to create ASP.NET Core Web API project in Visual Studio.

Once you provide the project name and location. Select Web Application(Model-View-Controller) and uncheck HTTPS Configuration. Above steps will create a brand new ASP.NET Core MVC project.

Showing project template selection for .NET Core MVC.

Setup a Database

Let’s create a database for this application using Entity Framework Core. For that we’ve to install corresponding NuGet Packages. Right click on project from solution explorer, select Manage NuGet Packages_,_ From browse tab, install following 3 packages.

Showing list of NuGet Packages for Entity Framework Core

Now let’s define DB model class file – /Models/TransactionModel.cs.

public class TransactionModel
{
    [Key]
    public int TransactionId { get; set; }

    [Column(TypeName ="nvarchar(12)")]
    [DisplayName("Account Number")]
    [Required(ErrorMessage ="This Field is required.")]
    [MaxLength(12,ErrorMessage ="Maximum 12 characters only")]
    public string AccountNumber { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Beneficiary Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BeneficiaryName { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Bank Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BankName { get; set; }

    [Column(TypeName ="nvarchar(11)")]
    [DisplayName("SWIFT Code")]
    [Required(ErrorMessage = "This Field is required.")]
    [MaxLength(11)]
    public string SWIFTCode { get; set; }

    [DisplayName("Amount")]
    [Required(ErrorMessage = "This Field is required.")]
    public int Amount { get; set; }

    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime Date { get; set; }
}

C#Copy

Here we’ve defined model properties for the transaction with proper validation. Now let’s define  DbContextclass for EF Core.

MVC User Registration & Login with ASP.NET Core Identity

User registration and authentication are mandatory in any application when you have little concern about privacy. Hence all most all application development starts with an authentication module. In this article, we will discuss the quickest way to use **ASP.NET Core Identity for User Login and Registration **in a new or existing MVC application.

Sub-topics discussed :

  • How to add ASP.NET Core Identity to MVC application.
  • Customize ASP.NET Core Identity.
  • Identity.UI Design Customization.
  • Next step.

Background

ASP.NET Core Identity is an API, which provides both user interface(UI) and functions for user authentication, registration, authorization, etc. Modules/ APIs like this will really be helpful and fasten the development process. It comes with ASP.NET Core Framework and used in many applications before. Which makes the API more dependable and trustworthy.

ASP.NET Core MVC with user authentication can easily be accomplished using Identity.UI. While creating the MVC project, you just need to select Authentication as Individual User Accounts.

Showing how to create an MVC application with ASP.NET Core Identity API

The rest will be handled by ASP.NET Core Identity UI. It already contains razor view pages and backend codes for an authentication system. But that’s not what we want in most of the cases. we want to customize ASP.NET Core Identity as per our requirement. That’s what we do here.

Create an ASP.NET Core MVC Project

First of all, I will create a brand new ASP.NET Core MVC application without any authentication selected. We could add ASP.NET Core Identity later into the project.

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N). From new project window, select ASP.NET Core Web Application.

Create an ASP.NET Core Web application

Once you provide the project name and location. A new window will be opened as follows, Select _Web Application(Model-View-Controller), _uncheck _HTTPS Configuration _and DO NOT select any authentication method. Above steps will create a brand new ASP.NET Core MVC project.

In this article, you will learn how to use or integrate WordPress in ASP.NET and Running WordPress on ASP.NET Core, without PHP, or any source files on the server. The following demonstration will show you how to add WordPress as a frontend to an existing ASP.NET Core application step by step.

Running WordPress on NET Core

WordPress is a free, simplest, and most popular open-source content management system to create your own website or blog which is written in PHP and paired up with MySQL. WordPress on .Net Core is possible with peachpie, which is a compiler built on top of the Roslyn platform, it’s a set of runtime and base class libraries and everything that allows compiling a PHP project, a group of PHP files into a regular .net project.

Peachpie allows for seamless both-way interoperability between PHP and .NET applications. In simpler terms, this means that one can have some parts of an application written in PHP, while other modules are written in .NET and everything will work together as one application. Here is the original Repository of the WordPress SDK by PeachPie.

Here are the following steps to run WordPress with ASP.Net Core:-

Step1: Open your Visual Studio IDE and Create a new project – > ASP.NET Core Web Application
