asp.net identity is a membership system that adds login functionality to your application. it is flexible, allowing you to create user accounts, manage user roles, and implement authentication and authorization features easily. in this tutorial, i'll walk you through the steps to set up asp.net identity in an asp.net mvc application, including user accounts and roles.

prerequisites

- visual studio 2019 or later
- .net sdk installed

steps to create an asp.net mvc application with identity

step 1: create a new asp.net mvc project

1. open visual studio.
2. go to `file` `new` `project`.
3. select `asp.net web application (.net framework)` from the options.
4. name your project (e.g., `identitydemo`) and click on `create`.
5. in the dialog, choose `mvc` and ensure that the `authentication` is set to `individual user accounts`. this will scaffold the necessary identity files for you.

step 2: examine the identity setup

after creating the project, you will see several files related to asp.net identity:

- **models/applicationuser.cs**: this class represents a user in your application.
- **startup.auth.cs**: this file configures authentication middleware.
- **controllers/accountcontroller.cs**: this controller handles user account actions like login, register, etc.
- **views/account**: contains views for login, register, etc.

step 3: configure the database

by default, your application is configured to use entity framework with a localdb database. you need to apply migrations to create the necessary database structure.

1. open the `package manager console` (`tools` `nuget package manager` `package manager console`).
2. run the following commands:



these commands will create the database and all necessary tables for asp.net identity.

step 4: create user roles

you can create user roles using the `rolemanager`. let's modify the `accountcontroller` to include role management.

1. open `accountcontroller.cs`.

2. inject `rolemanageridentityrole` in ...
