Configuring Email Sending in ASP.NET Core for Identity Library

ASP.NET Core is a powerful framework for building web . One common requirement in web applications is the to send , especially when it comes to user authentication and reset functionalities. In this article, we will explore how to email sending in ASP.NET Core for the Identity library.

Step 1: Setting up SMTP Configuration

The first step is to configure the SMTP settings in your ASP.NET Core application. SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails over the internet. To configure SMTP, open the .json file and add the following section:

  "EmailSettings": {
    "SmtpServer": "your_smtp_server",
    "Port": 587,
    "": "your_username",
    "Password": "your_password"

Replace your_smtp_server, your_username, and your_password with your actual SMTP server details.

Step 2: Implementing Email Service

Next, we need to implement an email service that will be responsible for sending emails. a new called EmailService.cs and add the following code:

The EmailService class takes an instance of in its constructor, which allows us to access the SMTP configuration values from the appsettings.json file. The SendEmailAsync method sends an email using the configured SMTP server.

Step 3: Registering Email Service

To make the EmailService available for dependency injection, we need to register it in the ASP.NET Core application's service container. Open the Startup.cs file and add the following code inside the ConfigureServices method:

This code registers the EmailSettings class with the values from the appsettings.json file and configures the EmailService class for dependency injection.

Step 4: Sending Emails

In this example, we inject the EmailService into the RegistrationController and use it to send a confirmation email after user registration.


In this article, we have learned how to configure email sending in ASP.NET Core for the Identity library. By following the outlined above, you can easily integrate email functionality into your ASP.NET Core applications and enhance user experience.
