Asp net identity vs asp net identity core differences and usage with identity s

Introduction

ASP.NET is a popular programming language used for building web applications. One of the key features of ASP.NET is its identity management system, which allows developers to handle user authentication and authorization. In this article, we will explore the between ASP.NET Identity and ASP.NET Identity Core and discuss their usage with identity.

ASP.NET Identity

ASP.NET Identity is a framework that provides a set of APIs for managing user authentication and authorization in ASP.NET applications. It is built on top of the ASP.NET Membership system and provides a more flexible and extensible solution for identity management.


// Example code for ASP.NET Identity
public  ApplicationUser : 
{
    // Additional properties for the user
}

public class ApplicationDbContext : IdentityDbContext
{
    //   for ASP.NET Identity
}

ASP.NET Identity allows you to define custom user properties by extending the IdentityUser class. You can then use the ApplicationDbContext class to interact with the database and perform operations such as user registration, , and role management.

ASP.NET Identity Core

ASP.NET Identity Core is a newer version of ASP.NET Identity that is designed to work with ASP.NET Core, the cross-platform successor to ASP.NET. It provides similar functionality to ASP.NET Identity but with some differences in terms of architecture and usage.


// Example code for ASP.NET Identity Core
public class ApplicationUser : IdentityUser
{
    // Additional properties for the user
}

public class ApplicationDbContext : IdentityDbContext
{
    // Database context for ASP.NET Identity Core
}

ASP.NET Identity Core follows a similar pattern to ASP.NET Identity, allowing you to extend the IdentityUser class and use the ApplicationDbContext class for database operations. However, it is designed to be more and modular, it easier to integrate with ASP.NET Core applications.

Usage with Identity

Both ASP.NET Identity and ASP.NET Identity Core can be used with the identity system in ASP.NET. The identity system provides a set of APIs and middleware for handling user authentication and authorization in ASP.NET applications.

Here is an example of how you can use ASP.NET Identity with the identity system:


// Example code for  ASP.NET Identity with identity
services.AddIdentity()
    .AddEntityFrameworkStores()
    .AddDefaultTokenProviders();

And here is an example of how you can use ASP.NET Identity Core with the identity system:


// Example code for using ASP.NET Identity Core with identity
services.AddIdentityCore()
    .AddRoles()
    .AddEntityFrameworkStores()
    .AddDefaultTokenProviders();

Both examples show how to configure the identity system to use ASP.NET Identity or ASP.NET Identity Core with the specified user and role classes, as well as the database context.

Conclusion

In conclusion, ASP.NET Identity and ASP.NET Identity Core are both powerful frameworks for managing user authentication and authorization in ASP.NET applications. While ASP.NET Identity is designed for use with traditional ASP.NET applications, ASP.NET Identity Core is tailored for ASP.NET Core applications. Both frameworks similar functionality and can be used with the identity system in ASP.NET.
