Adding Google Authentication In .Net Core Application Without Identity The Basics

Having a flexibility of creating a login logic can have many benefits to enjoy your self logic on to the application for authorization. So today here we will get the idea of going through Google Authentication in a .Net Core Application on a step wise process.

Note: The demonstration does not contains full application scenario (Complete Application) but have all the basic details needed which can be used to handle the details with self logic for your application needs.

Part 1 : Google Console Setup

First we need to have Google Client Id And Google Client Secret so for the purpose,

Login To Google Console and create a new New Project as

Now we need to enter a project name so as to distinguish each application, the organization field can be left as it is if you don’t want to have any organization.

Now, we need to move to Credentials menu as per the image below

Since we are creating an application for the first time we need to Configure Consent Screen which will be displayed when user chooses to login through Google.

Now, once we click on the button the below screen is displayed not choose External since the application is for any external users and click on Create.

Now, we need to enter a App Name and support and developer email address to create an app, the app creation and its use is shown below

Now, since we are doing the work with minimum configuration we can save and continue until the last, if you want to explore more every step will be presented with very descriptive details on the portal itself.

Here the app creation concludes now we need to move to credentials menu and create a OAuth Client ID as per the image below

Now we need to configure by choosing Application Type as Web Application and a client name as in the image below. Now Authorized Redirect URLs are the URL used for the redirection of the Google Authentication after success or failed attempt. The URL must be application URL. Since we are using ta local application we have used local urls.

Once clicked on Create we will be presented with the Client Id and Client Secret Id

Now we have completed the setup part on the Google Portal and have got the required

  1. Client Id
  2. Client Secret

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_._

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.

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.

So in this tutorial, let’s look how to customize the ASP.NET Core Identity.

Create an ASP.NET Core MVC Project

First of all, I will create a brand new .Net Core MVC application without any authentication selected. then ASP.NET Core Identity can be added to the project with the help of the _Identity Scaffolding _template.

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N). From New Project window, Select Asp.Net Core Web Application.
